[PATCH v2 0/2] MR244: winex11.drv: Keep GLX pbuffer alive while its drawable is used
Other drawable types are ref counted and destroyed only when nothing (e. g., existing contexts) reference them anymore, making sure that if we have a context referencing drawable the GLX drawable is still valid. That was probably left behind for PBuffers. -- v2: winex11.drv: Destroy GLX pbuffer when destroying drawable. winex11.drv: Store sgl_drawable instead of GLX drawable in wgl_pbuffer. https://gitlab.winehq.org/wine/wine/-/merge_requests/244

I think there is a typo in the first commit's message (sgl_drawable -> gl_drawable) but otherwise it looks good to me. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/244#note_2347
