Description miklos 2016-06-12 14:06:11 UTC

The "suspend compositor for full screen windows" option used to suspend it only while the full screen window was active. Now it is suspended while there is a full screen window even if it is in the background (minimized).

Reproducible: Always

Comment 1 Thomas Lübking 2016-06-12 14:09:30 UTC

The setting is irrelevant (and works differently and not at all on intel chips), the window asks to avoid the compositor.
See dupe and notably https://bugs.kde.org/show_bug.cgi?id=361091#c3 on how to override the (or all) clients opinion.

OK, I see that kwin now uses the _NET_WM_BYPASS_COMPOSITOR hint. In my opinion that is a stupid thing to do. For example, Team Fortress 2 disables the compositor while it's running, even if it's in the background, but Garry's Mod doesn't disable it at all. I mostly use composite effects for window management, so disabling the compositor also deceases usability for me.
