I can report I get this with annoying regularilty, Kubuntu 15.10, NVidia (HP
Envy laptop). It seems to have occurred since 15.04: a window simply stops
being refreshed unless it is resized.
The problem is attached to the window, not the application: using Chrome or
Firefox, I can drag a tab out into its own window and that new window updates
fine, I can even drag all the tabs one by one onto the new one until the old
window is empty (and thus destroys). (Until it occurs again on the new window,
sigh!). Not all applications can be recovered this way . It's particularly
annoying with virtual machines where the only way to get a new window is to
shut the VM down (or at least, sleep it).
I have not found any pattern in when a window decides to stop updating.
(A second thing that may or may not be related, but I'm mentioning it for
completeness: if I plug in a second monitor , then I also get a lot of tearing
or incomplete paints. I first noticed this on a image view program - as each
new image was displayed it would be blurry or leave some of the previous image
in view. It's not just that program, seen it with Virtualbox as well. However
in this case, wiggling the mouse forces the window to paint correctly, even if
the mouse doesn't travel over the corrupt area; and I've only ever seen it
happen on the external monitor).
I'm very interested to hear that kwin_x11 --replace might solve/reset the
problem, I'll definitely try this next time.
I notice bug is 12 months old, about 4 people are reporting it, yet it still
has status "unconfirmed". What does it take to confirm a bug then? <g>
