[Bug 26512] New: winex11 : pixelformat_from_fbconfig_id() : crashes when calling GetDC() with OpenGL window

Summary: winex11 : pixelformat_from_fbconfig_id() : crashes
                    when calling GetDC() with OpenGL window
           Product: Wine
           Version: 1.3.16
          Platform: x86-64
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown

wine test app (captures another window by title)

When an app tries to capture the window of other apps it works with simple 2d
apps but with 3D apps (OpenGL/DX) it causes wine to crash.

The crash seems to happen in pixelformat_from_fbconfig_id() function which is
in wine/dlls/winex11.drv/opengl.c

I've create a sample app to show this bug (winetest.cpp)

Run wine's notepad and then run:
  winetest.exe "Untitled - Notepad"
and it generates winetest.bmp no problem.
But if you run a 3d app (say SuperTux for Windows in OpenGL mode) it crashes.
  winetest.exe "Supertux 0.1.3"

You can download SuperTux from http://supertux.lethargik.org/download.html for
testing, or any other 3d app should work.  Make sure to download the Win32
version and go into options and turn off full screen mode and turn on OpenGL
mode then try the winetest.exe above.

I'll attach winetest.cpp, winetest.errlog and winetest.exe compiled with cygwin
(if permited).

To compile with cygwin : "gcc-3 winetest.cpp -o winetest.exe -l gdi32
-mno-cygwin"
Or try winegcc (doesn't work on x64 systems).

Thanks!

Putting 
  return 0;
in the first line of pixelformat_from_fbconfig_id() function in
dlls/winex11.drv/opengl.c makes it work.
So the problem is in one of the functions it calls.
Obviously this is not a fix but it narrows down the problem.

The call to pglXGetFBConfigs() is where the crash occurs.  It's an OpenGL
function.

If I create a Direct3D window in winetest.cpp before I try to capture SuperTux
it works.

Looks like OpenGL isn't initialized before winetest calls GetDC().

I haven't noticed a OpenGL / D3D situation like this before and I have no idea
if it could work at all. That said, try to add a line like this to the start of
pixelformat_from_fbconfig_id:
if (!has_opengl()) return 0;

It would trigger initialization of the OpenGL code. Though I have no idea what
will happen ..

Yes, that works.

I think this would also fix one of codeweavers reported bugs.

Except for the crash does it capture the 3D output correctly? Try a bunch of
different games to be sure. We don't hit the same code path for everything.

I tried another game and it's just the same as SuperTux.

I wouldn't worry about this bug.  The program that crashes is my own and I know
how to work around the issue.  I doubt many other non-gui apps do window
captures.  It's just a utility that I made.  If the fix might degrade
performance I wouldn't implement it.

Thanks.

This ticket has not been updated for over 900 days. Development recommends
to check the status on your bug every release or two and let to be known if the
bug is still present. If not, mark it fixed. If you are no longer able to put
effort to this ticket, you can abandon it.

Is this still an issue with 1.7.2 or higher ?

I am unable to test this bug anymore, but it no longer effects me.  You may
close if you like.
