As Bitwig still shows this misbehaviour I was searching for a different way as setting Windows to 100% is a no-go for my old eyes...
At least for Windows I found a solution:
Change the compatibility settings to this (some might know this workaround from Ableton!):
- Create a link for Bitwig on your Desktop if you haven´t already
- rightclick the link and open Properties
- navigate to the compatibility tab
- click on change high dpi settings
- activate overwrite high dpi scaling
- set overwrite mode to aplication
- confirm with OK
(reminder: german Windows here... I have guessed the english terms!)
Starting Bitwig with this setting doesn´t have any negative side effects for me (at least nothing I could figure out) but mouse wheel now works as expected on the trouble VST(i)´s!
As already said I have a german Windows here but I though attaching the screenshot might help anyway to find the right items if my translation should be too confusing...
