started a while back on my F22 system and is continuing on the F24
system.
What I switch workspaces I often get a screen that looks something
like a desktop snapshot. It goes away when I move the mouse, kind of
block by block. An <alt-tab> to a different app on the switched-to
workspace causes a complete repaint of the proper app and an
<alt-tab> takes me back.
This has been a pain for some time.
Then I noticed that if Firefox was busy on one workspace, the one I
was on would switch to this fake screenshot. I would try and get
back the active screen, but the screenshot keeps coming back until
Firefox is done doing whatever it is doing (like reporting the
progress of a file download).
Firefox seems to be really tied into this. But what might be the
problem and how do I report this as a bug. My weak search foo has
not found any thing reported like this.
Guidance on resolving/reporting this is greatly appreciated.
Can you look at xfwm4-tweaks-settings -> Compositing
and see if enabling that "fixes" the issue?
Or if it's enabled, you could try disabling it. It seems like a
compositor related bug to me.
