Bug ID: 360892
Summary: Plasma hangs when tooltip/popup is shown
Product: plasmashell
Version: 5.6.0
Platform: Gentoo Packages
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: igor.pobo...@gmail.com
CC: bhus...@gmail.com, plasma-b...@kde.org
If I hover mouse over any taskbar item, a tooltip is shown. Right after that,
whole system freezes for about 60 seconds (I can say that looking on my clock
applet, which jumps to current time when system unfreezes). During the freeze I
still can move my mouse around, but I cannot do anything else, I cannot even
switch to console to see what happens.
I was able to connect to my laptop from another computer via ssh, and "top"
showed "X" process eating 100% CPU during the freeze.
Surprisingly, it happens even when I disable compositing!
It also happens when I want any popup to be shown, not just a tooltip (e.g I
expand system tray, or look at plasma-nm applet, or devices widget). And it
also happens with Application Dashboard widget, which isn't a popup but a
fullscreen widget.
Reproducible: Sometimes
Steps to Reproduce:
Moving mouse around taskbar to create several different tooltips freezes the
system, but sometimes not after the first tooltip.
I have following graphics system:
00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT Integrated
Graphics Controller (rev 0b)
09:00.0 3D controller: NVIDIA Corporation GK208M [GeForce GT 730M] (rev ff)
My primary graphics device is intel. I use xf86-video-intel 2.99.917 and Mesa
11.1.2.
