           Summary: 32-bit game Dark Age of Camelot slow memory leak leads
                    to crash since WINE 7.4
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: d3d
          Assignee: [e-mail]

I've bisected a bug relating to a possible memory leak in wined3d. I've been
playing an old game (Dark Age of Camelot) for years now on free servers, but I
noticed there is a slow memory leak as it runs. I ran 'top' and watched the RES
memory creep up to 1.0 GB and then hit about 1.2-1.3 GB before the game
crashes.

On WINE 8 this issue seems to persist as well. So I went back and bisected the
bug and it occurs between WINE 7.3 and 7.4. In 7.3, I don't get the memory leak
and the game plays for hours, but in 7.4 I get the memory leak.

I've narrowed it down to this commit:
https://gitlab.winehq.org/wine/wine/-/commit/ee12556960e30fc22f276d2de2833e6...

It might have to do with the code change in the function
wined3d_context_gl_destroy_bo that introduced this.

Happy to try any patches to test with against latest WINE 8.x tree.

Thanks,
Tom
