Bug ID: 382817
Summary: Choppy and, generally, problematic KWin effects
Product: kwin
Version: 5.10.4
Platform: Other
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: effects-window-management
Assignee: kwin-bugs-n...@kde.org
Reporter: tsujan2...@gmail.com
Target Milestone: ---
Since KWin(X11) V5.10 (or maybe 5.8) and with kwin effects enabled, when I open
a window (like that of Konsole) and try to move it immediately after that, or
when I close a window and try to open a menu immediately after that, or when I
close a window and try to open another one immediately after that, or..., in
the first case, the movement is very jerky, in the second case, the menu is
opened badly depending on the effect (with the fade effect, it's
semi-transparent and unusable for a second), in the third case there's a
tangible delay, etc. Generally, kwin effects have recently been interfering
with other jobs. This happens with all sorts of effects, for example, those
I've made with translation, rotation, fading, etc.
The bad performance is visible in both Manjaro (Testing) and Debian (Unstable).
None of this happens with Compiz (https://github.com/compiz-reloaded) on the
same computer and with the same Linux distro (Manjaro Testing). Actually, that
old Compiz and its various effects work like a charm after so many years!
