Public bug reported: A mesa GLX change (somewhere between the 20.0.4 and 21.0.3) causes both wine and Proton (on an older system that does not have Vulkan.. SandyBridge, OpenGL 3.3..) to exit with GLXBadFBConf when it tries to fire up OpenGL.
Wine, for Direct3D support it tries to fire up (in order) Vulkan then progressively older OpenGL versions fro 4.5 down to 2.1 or maybe even 1.4 (of course the older the OpenGL the lower supported Direct3D version). Wine does not like getting an error back with the same transaction serial number as it sent out. See https://gitlab.freedesktop.org/mesa/mesa/-/issues/3969 Mesa issue 3969, The patch there throws in an "XNoOp()" to increment the transaction serial number. But the patch there caused issues in other apps, per https://gitlab.freedesktop.org/mesa/mesa/-/issues/4763 Mes issue 4763, They found XNoOp() increments the serial number, but xcb keeps a "shadow copy" of the serial number which is not incremented, causing problems. XFlush() increments the serial number, keeps xcb in sync and happy, with no real side effects (running XFlush() frequently would slow things down, but this code only runs when a GLX context is being created anyway which just doesn't happen all that frequently.) Please find attached a patch implementing the updated patch suggested in issue 4763.
