Bug#873290: xwayland: freeciv extremely slow, Xwayland using 85% CPU
Package: xwayland
Version: 2:1.19.3-2
Severity: normal
After upgrading my debian testing, I noticed that freeciv is unplayably slow.
Changing the view takes several seconds while the process Xwayland is shown
taking 85% CPU in 'top'. Previously it was almost instant. Additionally, just
showing a small animated circle around the focused unit is sluggish, also
showing 85% CPU usage.
A similar high CPU usage is shown in the game Battle for Wesnoth, which I think
is using SDL instead of gtk. This is why I report it as an xwayland problem
first, even though it might be a problem with this individual applications.
Some additional possibly relevant information:
freeciv-client-gtk: 2.5.7-2
wesnoth: 1:1.12.6-1
xserver-xorg-video-nouveau: 1:1.0.15-2
Most other applications does not seem to have the same problem. The schematic
drawing in KiCad shows the same high CPU usage but is as sluggish as usual.
Firefox or gimp does not have problems. Gnome is fine.
Note that I have not opted to use xwayland - this is something that has
recently changed for me automatically, so I'm not completely sure about exactly
which package this should be reported on.
