Flickering when clicking Add a new language in Languages settings

[Semel]

Hello.

I've installed Kubuntu 19.10, updated it, and added backports PPA (for newer Plasma version).

It seems to be working fine except for one thing. When I click "Add a new language" button in "Languages" (Settings) the "Add..." window starts flickering wildly.

You can see it here

If I resize "Settings" window to anything but full-screen then flickering stops.

Kubuntu is running on an all-in-one PC (i3 with Intel HD Graphics 530, 16GB RAM)



Any tips would be much appreciated.

Cheers!

When I have a problem like this I usually first disable/change the compositor settings to see if it persists. With that some of the transparency effects might not work though. Will see if I can reproduce this on Intel HD 630

here is my inxi output if it helps

I tried disabling composition, switching to xrender, trying opengl 2.0 and 3.0 but it hasn't helped.

I also tried using different 20-intel.conf configs but alas to no avail.
