Btw. isn’t it better to use the graphics settings in Windows? Add Cubase as an application there and then set the GPU mode to high performance in the options. Then the mode is only activated when Cubase is running…
Ok, you can’t tell from the screenshot whether these are the global settings. Hmmm… but I can’t imagine it fixes the errors. Many people have these issues with Cubase 13, so it’s probably more of a Cubase bug when rendering the UI.
For example, I often don’t see inserts in the new view in the side panel. The GUI element is simply not redrawn correctly or does not pick up the current data. This could be related to your error in the arranger window: missing redrawing of elements or redrawing with changed data
