[Bug 14640] New: OpenGL example from Lazarus fails at ChoosePixelFormat

Summary: OpenGL example from Lazarus fails at ChoosePixelFormat Product: Wine Version: 1.1.0 Platform: Other OS/Version: other Status: UNCONFIRMED Severity: major Priority: P2 Component: winex11.drv AssignedTo: wine-bugs@winehq.org ReportedBy: bugzilla@tut.by

Created an attachment (id=15048) --> (http://bugs.winehq.org/attachment.cgi?id=15048) log of demo being run under WINE with debug options

Just compiled an example of OpenGL usage for Lazarus (http://lazarus.freepascal.org/). While compiled for GNU/Linux+GTK+ target it works fine, Win32 target works on winxp but fails on WINE. The sources of the main program can be found here: http://svn.freepascal.org/svn/lazarus/trunk/examples/openglcontrol/ The sources of component's part which itself initializes OpenGL is here: http://svn.freepascal.org/svn/lazarus/trunk/components/opengl/glwin32wglcont...

--- Comment #7 from Rico kgbricola@web.de 2008-08-03 05:45:18 --- Do you think that's the right behaviour? (from your code) // get pixelformat FillChar(pfd,SizeOf(pfd),0); with pfd do begin nSize:=sizeOf(pfd); nVersion:=1; dwFlags:=PFD_DRAW_TO_WINDOW or PFD_SUPPORT_OPENGL; if DoubleBuffered then dwFlags:=dwFlags or PFD_DOUBLEBUFFER; if RGBA then dwFlags:=dwFlags or PFD_TYPE_RGBA; iPixelType:=24; // color depth -> this isn't the color! This has to be iPixelType:=PFD_TYPE_RGBA, the color is cColorBits:=24; cDepthBits:=16; // Z-Buffer iLayerType:=PFD_MAIN_PLANE; end;

But the question is, why does this work on windows (doesn't it?) and not on wine! Probably there are some test cases needed.

if RGBA then dwFlags:=dwFlags or PFD_TYPE_RGBA;

PFD_TYPE_RGBA isn't a valid flag.

This patch makes the test above happy. So that only one failing case (PFD_TYPE_COLORINDEX) is there.

Do you think that's the right behaviour? (from your code)

Note: this code is not mine. I don't use windows, I just use this unit and WINE to ensure my program will work for windows users.

iPixelType:=24; // color depth -> this isn't the color! This has to be
iPixelType:=PFD_TYPE_RGBA, the color is cColorBits:=24;

I will file a bug at Lazarus' bug tracker, so I hope this will be fixed. Thank you for investigation :-)

patch to pass the tests

This patch makes the test above happy. So that only one failing case (PFD_TYPE_COLORINDEX) is there.

Can this patch be committed into Wine? It could fix the problem from Wine's side too, as there can be many programs initializing GL in a such wrong way, and windows allows this to run.

--- Comment #13 from Rico kgbricola@web.de 2009-01-19 12:51:31 --- I'll submit it. The only problem is the testcase. It looks like the linux opengl drivers didn't offer PFD_TYPE_COLORINDEX. So there is a failing test in my example. Probably I'll change the test, so that it will not check for PFD_TYPE_COLORINDEX.

--- Comment #14 from Roderick Colenbrander thunderbird2k@gmx.net 2009-01-19 14:13:44 --- The problem is not limited to just this option but to most of the pfd options. I don't think windows is rewriting the format to RGBA but it likely just ignores this flag altogether. There are several problems. First of all the behavior of ChoosePixelFormat is not well defined and second parts of it are implemented in the icd of a vendor :( Because the behavior isn't well defined we don't know what microsoft is doing on the pixel format table. We have had similar issues with other options.

In order to fix this bug (and all the others) we need to know exactly what Microsoft is doing :( Else I fear that we only make the issue a lot worse as right now our ChoosePixelFormat seems to work for most apps (it has been in a much worse state).

The executable from #1 uses invalid values which are hard to find the correct solution for (see #14). Though the source for this is fixed, so a fresh build executable will run without trouble.

Attached is a rebased patch, which still is a hack.

For ePSXe, please attach a +wgl log.

confirming still present.

I've merged a few potential dupes here since the same patch helps there too. Due to the catch-all nature of the patch there is a risk they are still different problems on implementation details but no one seems to care to dig deeper.
