Same problem here with the 2023 IntelliJ community edition on Debian. Did you ever fix it @kammerer?

The bug reports will get more attention if more users are affected.

If you (member or lurker) find the latest Ubuntu distribution gives you strain/discomfort please sign up to Launchpad and add yourself to the number of users affected.

@kammerer I assume you tried already the following methods described here?

Currently I run Ubuntu 19.04 with an NVidia card and Nouveau driver connecting to a CCFL display with a VGA cable. This is working pretty well! Also the internal display of the Thinkpad W530 using the descrete NVidia graphics chip with dithering disabled works quite ok.

Is using a different graphics card an option for you?

@kammerer, I too have similar problems. I still do not understand what the root cause is. But, the following are less problematic for me:

1. Ubuntu 18.10 (default desktop)
2. MX Linux (default desktop)
3. Manjaro KDE (non-free install)
4. Devuan KDE
5. PCLinuxOS

Hope one of these will suit you.
