--- Comment #15 from tempel.jul...@gmail.com --- With the default setting of keeping window thumbnails only for shown windows, the issue completely disappeared for me. Thanks to your rework and Proton's intelligent use of compositor suspend, I can finally really enjoy KWin compositing for the first time. With the patch you provided, the game still freezes with a black window when setting it to "always" and then alt + tabbing, so it has not changed. The same btw. happens also on Wayland, but not just with Plasma, also with Sway. So the issue might indeed lie in the Proton fullscreen hack, and not the compositors. For some reason it works with Gnome though. Workarounds are to switch to borderless mode in the Windows games or use a Wine virtual desktop. Regarding performance: In Heroes of the Storm, it's 154fps without compositor vs. 147fps with kwin-git. So it's a ~4.5% loss, which I think is fine. Windows DWM performs very similarly. I think KWin Wayland and Sway are a tiny bit faster though. But I personally really disdain compositor vsync in games in general, I can't stand the added input latency and uneven frame output due to repeated/discarded frames vs. direct tearing. ;) -- You are receiving this mail because: You are watching all bug changes.
