I use Cubase Artist 9.5.30. My screen resolution is 3840x2160 and font size at 250%.
When cubase loads the text size is as intended.
When I open the VST Transit from the menu, the font size for VST and Cubase reverts on 100% and makes the application unusable. The 100% text size stays till I close the application. When i open it again, it again goes on normal (250%) text size.
This happens on Cubase Elements 9.5 also.
Please take a look on it.
