Bug ID: 58592
           Summary: Font substitution partially broken - regression
           Product: Wine
           Version: 10.12
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown

While trying to replace "Tahoma" with "Noto Sans Regular" (the default Plasma
desktop font), I've encountered an issue, where the font replacement does not
work in some cases. Since I'm migrating from a very old system with Wine 1.6.2,
I know that the font replacement used to work for the exact same binary and the
same UI elements.

I've set the following registry keys:
[HKEY_LOCAL_MACHINE\Software\Microsoft\Windows
NT\CurrentVersion\FontSubstitutes]
"Tahoma"="Noto Sans Regular"
"Segoe UI"="Noto Sans Regular"
"MS Shell Dlg"="Noto Sans Regular"
"MS Shell Dlg 2"="Noto Sans Regular"

The issue can be reproduced by opening the file dialog in the built-in registry
editor.

Running the built-in registry editor I've got the main font changed to "Noto
Sans Regular" as expected, but in the file open dialog for import, there is
still "Tahoma". When I'm browsing for directories, the font changes to "Noto
Sans Regular", but when an item is selected, the font changes back to "Tahoma".

Here is a short video showing the issue: https://imgur.com/a/l0BhsB8

This is only one example of the non-working substitution. The "Tahoma" is also
rendered on the buttons and almost everywhere around in the dialog. I'm using
the substitution mostly for MikroTik network equipment management apps (WinBox
and The Dude) to improve the readability. It is working fine when running the
exact same binaries on the old PC with Wine 1.6.2, but I can't get it to work
with the newest Wine.

The system is KDE neon User, Plasma 6.4.4, Wine 10.12 from the WineHQ PPA.

As you may have noticed, plenty has changed since 1.6.2.

I'm not sure if it helps, but try using
HKEY_CURRENT_USER\Software\Wine\Fonts\Replacements key instead (and keep 32bit
vs 64bit in mind - sometimes you need to explicitly put in in the Wow6432Node
subtree).

Thanks for the help, but as you can see in the attached video, the issue is not
that the registry key is not read. The font is being replaced back and forth
upon selecting of an item, which is definitely not on purpose. That is why I'm
reporting this as a bug in the first place.

Also, I've got the "HKEY_CURRENT_USER\Software\Wine\Fonts\Replacements" set as
well just in case.
