--- Comment #4 from 1685899837@qq.com --- My testing environment：debian12 ,intel x86_64

After submitting this commit, the lifecycle of the OpenGL Drawable window remains consistent with the window. Perhaps there are still some issues with releasing OpenGL Drawable resources.

I have added logs of abnormal operation in the following reply, you can search for the location where the exception occurred:

--- Comment #11 from Rémi Bernon rbernon@codeweavers.com --- Thanks, I think compressing the log file could make it small enough for attachment, the +loaddll parts could be useful to figure if it's crashing in the application or in Wine modules.

Anyway, from the small portion it looks like it crashes after calling glGetString(GL_RENDERER) which maybe could indicate that it gets an unexpected or NULL value there:

http://bugs.winehq.org/show_bug.cgi?id=58831

--- Comment #13 from Rémi Bernon rbernon@codeweavers.com --- Thanks, the RIP / RBP register values at the crash site seem to contain invalid pointers, (0x000000293436646d, resp 0x612d34332d302e31). These are actually likely string bytes, as interpreting them as ASCII returns ")46dm" and "a-43-0.1", which when reversed and concatenated gives "1.0-34-amd64".

Elsewhere in the log we can see that the GL_RENDERER string that has just been queried is supposed to be "AMD Radeon Graphics (radeonsi, navi33, LLVM 15.0.6, DRM 3.49, 6.1.0-34-amd64)", which suspiciously matches the corrupted registers after 64 characters.

My understanding is that the application is querying GL_RENDERER, and copies the string in a 64byte buffer, overflowing it and corrupting the stack and later the registers when they get restored after some calls.

The issue is then unrelated to the blamed commit but that the GL_RENDERER string is too long, and that's a bug in the application, or in MESA. Still, it's probably something we can provide configuration option to workaround in Wine and I'll have a try at it.

Thank you very much. It is possible that this is the reason, but it did occur after merging this submission. There was no such issue during the compilation of wine in his previous submission.

Sorry, I had messed up the patch, this one should hopefully work and fix the crash.

Thinks, After applying the patch, there was no deadlock issue and the software could start normally. However, the right part of the interface after startup was originally a white interface. At the beginning of startup, it was a white interface, and then it turned into a black interface.

Overall I think this regression could be considered as resolved, but if the application still doesn't work as intended it'd maybe be better to open a separate bug.
