opengl32: Add a FIXME when doing a mapped buffer copy. (!4513) · Merge requests · wine / wine

Aida Jonikienė requested to merge DodoGTA/wine:mr/opengl-wow64-fixme into master Nov 26, 2023

I should've pushed this shortly after the workaround for the WineD3D WoW64 graphics corruption got upstreamed (which I discovered when messing around) but never got around to MR anything in Wine.

The copies of mapped buffers introduce significant performance overhead (I'll add a FIXME so that people don't get surprised when their old games run like a slideshow like for example NFS Most Wanted).
