Screenshot of tf2 demonstrating the scope redering upside down

In Team Fortress 2 (tf2) and Left 4 Dead 2 (l4d2). Certain effects are being
rendered upside down. I've noticed it on the sniper rifle scopes in both games,
and when under water or affected by jarate in tf2.

It seems switching my OffscreenRenderingMode from backbuffer to fbo corrects
this behavior.

I can confirm this bug to happen with HalfLife 2 with orm=backbuffer. This bug
was introduced somewhere between 1.3.4 and 1.3.8, can't tell more precisely as
it requires to do git bisect and I'm still having big troubles mainly due to
the lack of free time with setting up working development environment with git
installed on my home workstation.

This bug seems to also affect some other games. For example, in King's Bounty:
The Legend it would show itself in a load/save game window: small screenshot
thumbnails would be displayed (and thus saved) upside down with wine 1.3.8+
(tested with 1.3.8, 1.3.9 and 1.3.10), while would be ordinary oriented with
wine 1.3.4.

Looking at the version number the original bug reporter had specified I may
shrink "bug introduced in version" window to somewhere between 1.3.4 and 1.3.6.

Still exists as of Wine 1.3.11, tested with Half-Life 2. To get an idea about
what does the problem looks like and what a correct picture should be take a
look onto two screenshots I had recently attached to this bug report.

Confirmed in both Left 4 Dead and Left 4 Dead 2; the 3D world is always
upside-down. Haven't tried TF2.

Wine 1.3.11
Linux 2.6.36-ARCH

games tested.

Out of curiosity, why are you using backbuffer ORM?

This doesn't make the bug invalid, but backbuffer ORM is a somewhat odd setup
nowadays. Personally I'd prefer to remove it, so I am interested in the reasons
why people still use it.

It's the only way to get multisampling (antialiasing) working semi-correctly in
 HL2 under Wine nowdays. Having anti-aliased picture is a high priority for me
and I would prefer 40 FPS + working AA over the 90 FPS + no AA.

I can't reproduce this bug as of Wine 1.3.28.
Most like it's fixed.

This bug occurs for me again in The Elder Scrolls VI: Skyrim. During loading
screens and in the game world graphics are rendered upside down. Camera
movement flips everything back into place, but not permanently. Playing with
OffscreenRenderingMode=fbo is not an option, because the game tends to crash
with that setting.

I'm running Wine 1.3.32 on Arch 64.

Please do not confuse original bug which is only about some effects that had
been rendering upside-down - and not the whole "game world" - and it had been
happening in pretty small number of apps (confirmed to occur in all
Source-based games and at a pretty minor place in "King's Bounty" series) - and
not in each and every app out there. Would you please test it in some
Source-based game to prove that's it is the same bug flashback and not a newly
introduced independent one? I would be able to test it in HL2-series myself but
non earlier than tomorrow evening.

P.S. In case Skyrim had been working correct with older versions of Wine -
doing regression test and reporting a new bug would be your best way to
proceed.
P.P.S. Thanks for spending your time and reporting this issue.

Thank you for clarifying this. My apologies. Skyrim is obviously not an app
based on the Source engine, and I don't own one of these games, so I'm unable
to test for this bug.

I'm going to take your advice and do some regression testing, then proceed to
open a new bug report for this.

I had tested it yesterday with wine 1.3.33 in Half-Life 2 and Half-Life 2:
Episode 1 and can state that there this bug hadn't been reintroduced.
