Description of problem:
I'm playing osu! https://osu.ppy.sh/home on wine and I'm experiencing a big performance hit (240+ FPS => 20 FPS) after upgrading from F27 to F28 beta. The performance became bad only on the GNOME Wayland session, launching the Xorg session gives normal performance. Switching fullscreen on and off in-game makes no difference.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Launch the game on GNOME Wayland and observe the FPS
2. Launch on GNOME Xorg, or on F27 GNOME Wayland and observe the FPS
Bad performance (~20 FPS)
Good performance (240+ FPS)
Installing the game requires winetricks -q dotnet45 corefonts in a 32-bit wine prefix.
It became considerably better with the upgrade to GNOME 3.28.1: now I'm getting around 140 FPS in the same game in the menu on Wayland with about 180 on Xorg, and ~240 in-game in both cases which is good.
Another thing I noticed is the game tears on Xorg as it should (I have VSync disabled for reduced input lag and the game is running fullscreen), and it doesn't on Wayland (probably leading to input lag?), but that's unrelated to this bug.
I suppose this should be closed now, not sure what to pick in the status though, so please close this.
