Bug ID: 399041
Summary: Qt 5.11.2 causes stuttering
Product: ksplash
Version: 5.13.5
Platform: Archlinux Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: unassigned-b...@kde.org
Reporter: matthewtresc...@gmail.com
Target Milestone: ---
SUMMARY
After upgrading to Qt 5.11.2 from 5.11.1, the splash screen's circular
"loading" indicator stutters noticeably. Perhaps also related is that when
closing Chromium, KWin's fade animation is not smooth. I'm not sure why this
is. After I noticed this, I downgraded Qt to 5.11.1 and the problems went away.
Sorry to file this in such an obscure component. I suppose this bug will have
to be forwarded to Qt but I wanted some help triaging it first.
STEPS TO REPRODUCE
1. Upgrade to Qt 5.11.2
2. Log out
3. Log back in
EXPECTED RESULT
The splash screen's "loading" indicator spins smoothly.
ACTUAL RESULT
The "loading" indicator freezes for brief moments while it spins.
SOFTWARE VERSIONS
(available in About System)
KDE Plasma Version: 5.13.5
KDE Frameworks Version: 5.50
Qt Version: 5.11.2
ADDITIONAL INFORMATION
This is a very normal system with Intel Haswell graphics and I am using X11
(not Wayland).
