--- Comment #5 from debuser debuser1@mt2014.com --- I don't have non-nvidia cards to test, but I asked in #winehq and someone with ATI card said that elevated looks broken in wine-1.7.34 (which has bug 37723 fixed, and doesn't have bug 38477 introduced), but it looks correct in wine-1.3.23 (last pre-1.5.27 version that doesn't have bug 37723 and is able to run elevated).
Maybe it's not specific to Nvidia after all? Is it possible to write some test printing some debug information to run on different hardware and check if it behaves the same?
