Bug ID: 435138
Summary: Assume that all full-screen applications want to block
composition
Product: kwin
Version: git master
Platform: unspecified
OS: All
Status: REPORTED
Severity: wishlist
Priority: NOR
Component: compositing
Assignee: kwin-bugs-n...@kde.org
Reporter: es204904...@gmail.com
Target Milestone: ---
Composition provides no value when there's a full-screen application running,
for 95% of cases, and you can tell performance is smoother when turned off.
I don't know if the full-screen window is composited itself, but even if that
wasn't the case having the rest of desktop elements being composited does
nothing and decrease performance.
So it would be better disabling composition by default when there's a full
screen application, as kwin-lowlatency does, while perhaps allowing composition
for some full screen windows if they explicitly request so with a window rule.
