Hello,

I've recently updated from Leap 15.0 to Leap 15.1 on my laptop and now plasma
workspace is constantly broken as the following.

Please, see at the screenshot. Tiny bottom part of the main panel is missed.
Also, right part of the clock is missed too. This is 100% reproducible.

linux kernel is 4.12.14-lp151.28.7-default
plasma5-workspace-5.12.8-lp151.2.1.x86_64

I use Intel GPU: Intel Corporation HD Graphics 620 (rev 02)


I have no idea what additional software and hardware info may be related to
this issue, so please tell me what info I should additionally provide.
