Description Michał 2016-07-09 20:20:26 UTC
Display shows previous and last frames of animation switching between them randomly.
Example: moving cursor in Dolphin suddenly starts alternating highlights between two files.
Another example: after writing some text in Vim I see that text appearing and disappearing.

Video of unminimizing animation when this happened - looks like it started alternating between two last frames of animation → https://youtu.be/SpZdhF2WVXM

Happens from time to time… every 5 or 15 minutes maybe.
Started happening with Plasma 5.6.5.
Clicking on background image or other kind of interaction with the environment usually fixes the problem.

Reproducible: Always

Steps to Reproduce:
Do your usual stuff and wait patiently. ;-)



Two monitor setup - one is notebook display - 2.5K, second is external 4K display. Compositor effects are enabled.
Plasma version is 5.6.5.
Qt version is 5.7.
Graphics card: Intel Corporation Broadwell-U Integrated Graphics (rev 09)
Notebook type: Levono X1 Carbon (version 3)
