I’ve tested this with my setup and after upgrading to 4059 Amplitube no longer works correctly. It will open once correctly, but after that it is blank. I can fix by reverting to older versions including 4058
200% scaling in windows
“Enable Plugin GUI Up-Scaling” is off
“HI-DPI User Interface” is “Enabled & Upscale Plugins”
“Enable GPU Accelerated Rendering (OpenGL)” ON.
Changing the last 2 settings makes no difference.
Changing Scaling will show some of the interface depending on what you select when opening the gui the second time.
