Hey guys,

I just wanted to let you know that after running an update today to Plasma
5.7.1 (from Fedora packages) the described issue seems to be gone :-) So
whatever fixed it: Thank you a lot (also in general, so far I love the 5.7
release)!

Ciao
Martin

No problem, survived worse ;)

Regarding OpenGL: I tried to switch to 2.0 which does not change anything.
Switching to XRender makes some difference (there are still fragments seen on
the screen, but compared to OpenGL - where the fragments are kind of flickering
- with XRender the fragments are drawn steadily).

Sorry for your arm :-P

My guess is that the animation gets retargetted (seems to be quite required
reg. the tooltips)
Not only is this the least tested feature, but I assume that altering the from
to the current position drops the region between the last interpolated position
and the interpolated position at the repaint.

The most simple solution should be to add a complete (full scene) layer repaint
when an animation is retargetted.
If that works, one could seek into actually capturing the dropped geometry.

please also try using OpenGL 2 in KWin's compositing settings.

Switching to GLX did not change anything. What I just noticed is that the issue
also occurs on VD1, so this was a false trace (dunno why it did not seem to
happen on VD1 before, though...).

Regarding DRI3, this is what I found in the X log:

[14.847] (II) intel(0): direct rendering: DRI2 DRI3 enabled

So I guess DRI3 is in fact enabled already.

As recommended, I tried to disable the blur and contrast effects and enabling
the morphing popups effect, but the issue remains.

Looks more like insufficient repaint areas, but
a) that should affect more effects
b) the relation to the VD seems a bit odd.

please attach the output of "qdbus org.kde.KWin /KWin supportInformation" and
try whether this also remains w/ the morphing effect en-, but the blur and
contrast effects disabled.

Thanks, re-assigning to KWin and CC'ing Marco who wrote the morphing popups
effect.
