Check if an update of Java to the most recent version helps (>= Java 11).

Just tested it, no difference.

Can you please try to remove the jogl and kendzi3d plugins?

[Geimas5]

Unfortunately, removing those plugins did not change anything.

What's your graphic card model? Please check you're using the latest version of graphics drivers. This problem doesn't come from JOSM.
