Bug ID: 363500
Summary: Flickering and incompletely drawn textures
Product: kwin
Version: 5.5.5
Platform: Kubuntu Packages
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: andy...@mail.ru
Sometimes I can see flickering or incompletely drawn textures around the
desktop. For example, I once saw part of the Firefox window, which was opened
on one monitor, flicker on the other monitor (which had no open windows, i.e.
it flickered on the desktop). Another time window decorations were either
flickering or not drawn at all for different applications. I took a screenshot
of this case (attached). When I moved the mouse over the decoration, it starts
to flicker more frequently, and if I move mouse over the decoration buttons,
they are drawn in squares, with the rest of the decoration not drawn.
Reproducible: Sometimes
Steps to Reproduce:
I don't know a reliable way to reproduce this.
Kubuntu 16.04, x86_64. Nvidia driver 367.18. The flicker also happened with
364.19. OpenGL interface: GLX, rendering backend: OpenGL 3.1. Desktop theme:
Breeze, window decorations: org.kde.oxygen.
