Audacity 3.6.3 in Wine 9.17 with DPI=144 and classic Windows theme

After I upgraded Wine from version 9.10 to 9.17, Audacity has become horrible
to use and look at.

I've always been using DPI=144 because I have a High DPI 14" monitor.

So,

* Fonts in Audacity have become much smaller than they were before
 * Fonts now look very blurry

A screenshot will be attached.

On the outside of Audacity you can see IrfanView which continues to scale
properly and fonts are rendered just fine.

I could make a wild guess this is due to "Window surface scaling on High DPI
displays" but then the regression range is huge.

Also Wine spams:

"024c:err:font:alloc_font_handle out of realized font handles"

in console and I've no idea if it's a functional issue.

The DPI awareness is now application dependent, and some applications which are
system or per-monitor DPI aware are going to keep the original scaling
behavior. Applications which aren't DPI-aware are scaled to the configured
system DPI through a bilinear upscale.

This is similar to what Windows does, although it maybe has more advanced
scaling options which aren't implemented yet. We could also perhaps add a
registry setting to give the option to force the old behavior on all
applications, but it is not how Windows behaves and it can break some other
applications.

Is it possible to disable this new Wine's feature completely or for this
application alone in Wine 9.17 or I just have to downgrade for a while?

Secondly, bilinear scaling is so 2000.

Could you perhaps implement something more modern, e.g. B-Spline, Lanczos or
ewa_lanczossharp found in mpv?

**At the very least it would be nice to see Integer Scaling (nearest-neighbor)
in Wine.**

Oftentimes it looks better than any advanced floating point upscale algorithms
because it's just sharp.

And it's pretty much de-facto for console emulators.

There won't be much of a difference with any other kind of filtering, the
application draws at a lower resolution and whatever we can try to do about
won't restore the missing information.

Nearest neighbor gives very horrible results in this case, as it's not an
integral upscaling (well except if you use a multiple of the base 96 DPI).

There's a world of difference between e.g. bilinear and lanczos:

https://gitlab.winehq.org/wine/wine/-/merge_requests/6499 should probably help
with FAR.

FWIW I checked Audacity on Windows, and it has exactly the same behavior and is
just as blurry as on Wine now when scaling is used. This is something that the
application needs to implement, and it may be as simple as adding an executable
manifest that advertises system DPI awareness, not something that Wine can fix.

Sure, we could in theory try to implement smarter upscale filters, but that
would need specific code, and I'm not yet sure it's worth it, and may be
possible to do differently.

Sadly Wine 9.17 doesn't have this extract :-(

What it has is:

/* FIXME: what do the DpiScalingVer flags mean? */
    get_dword_entry( (union sysparam_all_entry *)&entry_DPISCALINGVER, 0,
&dpi_scaling, 0 );

if (volatile_base_key && dispos == REG_CREATED_NEW_KEY)  /* first process,
initialize entries */
    {
        for (i = 0; i < ARRAY_SIZE( default_entries ); i++)
            default_entries[i]->hdr.init( default_entries[i] );
    }

Yes, the line has been removed you need to add it back if you want all
applications to be system DPI aware.

Change:

```
    /* FIXME: what do the DpiScalingVer flags mean? */
    get_dword_entry( (union sysparam_all_entry *)&entry_DPISCALINGVER, 0,
&dpi_scaling, 0 );
```

to:

```
    /* FIXME: what do the DpiScalingVer flags mean? */
    get_dword_entry( (union sysparam_all_entry *)&entry_DPISCALINGVER, 0,
&dpi_scaling, 0 );
    if (!dpi_scaling) NtUserSetProcessDpiAwarenessContext(
NTUSER_DPI_PER_MONITOR_AWARE, 0 );
```

This works, thanks a ton! I've made a patch for those who want to fix Wine 9.17
in the meantime.

My thought is, if Windows does something but does it poorly... and it's
possible to do it better than Windows without losing compatibility with
programs, why not do it? I have at least 7 programs that I use, and before this
update, they worked wonderfully with Wine, even with fonts at 120dpi. Now
everything looks terrible. Please put things back the way they were before...
Anyway, I've never seen Windows blur the fonts of programs.

Not exactly "force the old Wine behavior", but Windows has
AppCompatFlags\Layers registry key to control app compatibility behavior
(including GDI scaling).

Couldn't we put a checkbox in Wine's graphic configurations to enable and

Unfortunately, I have a problem with this change as well. Applications with
high DPI settings are not only blurred but also very slow. For example, when I
use WinDjView https://windjview.sourceforge.io/en, the scrolling performance is
terrible, whereas at the standard 96 DPI, and with the proposed patch, it's
quite fast. Integer upscaling would also be a nice addition, provided it
doesn't slow things down like bilinear upscaling...

I don't know why, but since this bug doesn't seem to affect video games, I have
a feeling it will remain unresolved for years, like other bugs I've reported
that were completely forgotten because they relate to work and productivity
applications... The Wine team seems to care only about video games... In the
end, those who game on Linux typically use Steam's Proton at best... They
should give more consideration to things that aren't video games. For now, I've
forced the second-to-last version of Wine and blocked the packages to prevent
updates.

I understand that DPI awareness should be enabled by applications, but many
older applications work very well with higher DPI settings. In fact, I consider
it a "feature" that breathes new life into these older apps. I'm not suggesting
it should be enabled by default, but it should be an option, perhaps accessible
through the registry.

Since 6f44677c5fbc6b9677a72e27b8cb0a6e494dfad6 we now have support for the
AppCompatFlags registry setting, as documented in
https://ss64.com/nt/syntax-compatibility.html.

The setting can be set per-user (HKEY_CURRENT_USER\Software\Microsoft\Windows
NT\CurrentVersion\AppCompatFlags\Layers) or globally (
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows
NT\CurrentVersion\AppCompatFlags\Layers).

It can then be set for individual application (using the application path as
the value of the registry entry), or globally (using the default registry value
'@' for the key).

The data can either be set to DPIUNAWARE or HIGHDPIAWARE, to force application
DPI awareness to off or on respectively.

Are there plans to hack winecfg to make these things visual and manageable by

I add myself to the request, you need a flag in winecfg to be checked to
manually force the applications that create problems.

I'll consider it. In the meantime you can use the same command-line as is
documented. For instance forcing all applications to be HiDPI aware:

Thank you! It works for me. In the meantime, I looked into how Windows handles
high DPI settings. It appears that Windows simply upscales the interface, but
not the entire window. Only the toolbar and menu are upscaled, while the
content rendered by the program remains unaffected. For example, in WinDjView,
the interface is upscaled, but the displayed book is not. This explains why,
even in my Windows virtual machine, scrolling is as fast as it is on Linux with
96 DPI or the DPI-aware option enabled.

By the way for me only works for "HKEY_CURRENT_USER" (HKCU instead of HKLM)
i.e.

wine REG.exe ADD "HKCU\Software\Microsoft\Windows
NT\CurrentVersion\AppCompatFlags\Layers" /T REG_SZ /D "~ HIGHDPIAWARE" /F

Oh. I was running Satisfactory with DX12 renderer (in Wine 9.21) and couldn't
understand why the graphics were EXTREMELY pixelated despite the game being set
to 3840x2160.

Then I remembered this ticket and thought "could it really be running in
low-DPI mode"?

I ran this command:

wine REG.exe ADD "HKCU\Software\Microsoft\Windows
NT\CurrentVersion\AppCompatFlags\Layers" /T REG_SZ /D "~ HIGHDPIAWARE" /F

Voila, Satisfactory now renders at native 4K again.

This doesn't help for Audacity 3.7.1 but the patch still works in 10-rc3.

I've also tried:

~ DPIUNAWARE
~ GDIDPISCALING DPIUNAWARE
~ HIGHDPIAWARE

None of the works.

I have solved my problems with "REG.exe ADD "HKCU\Software\Microsoft\Windows
NT\CurrentVersion\AppCompatFlags\Layers" /T REG_SZ /D "~ HIGHDPIAWARE" /F" but
I still think it would be useful to have a checkbox in wineconfig to enable or
disable this feature. Regardless of Windows' behavior with certain old
applications, the result of disabling this function is significantly better
usability.

Morning, Gents.

I am on Debian with XFCE and last night I updated and upgraded, and then as
with others here, I found Wine apps now running at the wrong resolution (and so
for windowed apps, blurry, and for full-screen apps, the apps was showing the
normal resolution about 2.5k by 1.5k, but the *display* looked to be 640x480,
so top-left corner only of the app could be  seen), and running very slowly.

Wine was then unusuable, and I was at a loss as to what had happened or why.

After about 20 or 30 minutes of experimentation and Googling, I found this
thread, tried to make the solution work but to begin with failed, but in the
end achieved success with;

"REG.exe ADD "HKCU\Software\Microsoft\Windows
NT\CurrentVersion\AppCompatFlags\Layers" /T REG_SZ /D "~ HIGHDPIAWARE" /F"

(But that HKCM specifically did not work - I needed HKCU.)

From my point of view, Wine was broken after update, and needed 30 minutes of
Googling to fix.  If this were to be a common experience, it would cause
substantial disruption.

Finally, note there is one new problem; from the single full-screen app I use,
I can now alt-tab to the Linux desktop exactly *once* before the display of the
app goes black, i.e. the screen display is now simply a black screen, and so
the app must be killed from the Linux command line and then restarted.

It used to be I could alt-tab quite a bit, maybe ten times, but in the end
textures would not load, and then I would need to quit (which I could do in the
normal way, and restart.)

This seems to be a separate issue. Can you file a bug for that, ideally with
bisected regression?

Done.
