There is already already a long thread I created about this (and other design problems in Cubase 13+):
I and other people have the exact same problems especially with the font sizes on higher screen resolutions. I also opened a support ticket with Steinberg regarding those issues.
Steinberg replied to both my ticket and in the thread, not really admitting that there is a problem, but that they are “taking the criticism into consideration”, promising nothing of course, but I think we’ve made ourselves heard a bit.
