Menu gets vertical

I’ve encountered a bug where right clicking to try and add a new track shows a menu that is unusable

  1. Use Cubase 10.5.2
  2. Leave it on for a night or several hours
  3. Now the menus are vertical

    It also seems to affect the channels, where it is no longer possible to add/remove insert effects. It has persisted right from Cubase 10 as far as i remember.

Win10, I7 6700K, Saffire pro 40, 16GB ram

I’ve seen this from time to time as well. It seems to affect a wide variety of menus once it happens.
