While Wine does something incorrect here, shouldn't amdgpu/radeonsi still
handle such kind of issues more gracefully? I.e. while Wine should be fixed, I
think Mesa shouldn't cause a system freeze when that happens. Can your patch
approach be generally useful for Mesa to make it more resilient, or some other
solution would be needed?
