graphic errors after doing some actions

[protoxenus@…]

Hi,
I was updating my computer with a new processor (i7 9700), a new motherboard (Asus Z390) and new RAM (32 GB) to get a better performance in simulation. Since then while using JOSM with any pixel graphics (JPEG pictures or background air picture) after a couple of minutes JOSM is nearly unusable. All elements are partially overwritten by picture elements and all operation windows opening up incomplete or partially double.
This problem appears only when using JOSM.

What steps will reproduce the problem?

as described above

What is the expected result?

stability

What happens instead?
