Some recent package upgrade in Stretch (I'm trying to pin down which)
has caused parts of my Plasma desktop to freeze at seemingly random
intervals. When it happens (every few minutes), all windows continue
to behave normally, and new programs can be started with
alt-F2. However, the desktop area itself, the taskbar and any
notifications become unresponsive. Switching to a console and then
back to X, without doing anything else, makes everything work again
for a while.
This seems to be exactly what is described in a recent Fedora bug .
Before I file a bug and investigate further: is anyone else
experiencing the same thing? Does anyone have any idea as to which
upgrade may have caused the problem? I can't believe the update
happened more than a week ago.
