Public bug reported:
The graphical environment seems to hang when scrolling web pages in
Firefox. Can't reliably reproduce during every scrolling, but it has
happened at least 5 times in the past 7 days. Happens in Kubuntu VM-s
running under KVM and QEMU (3.1.0) on multiple host machines.
This issue only started to happen sometime this month. First these VM-s
were running 18.04 so I was hoping that updating them to 18.10 would
help, but it didn't. I'm guessing that some kernel update for both
bionic and cosmic causes this.
Since this bug causes the graphical environment to become totally
unresponsive, this has already already cost me some lost data, but very
fortunately not much.
