I'm joining this thread instead of the previous one I created so that the info is not lost.
I just ran a quick test on my laptop with B839.
When running CMANO in my "old way" (meaning screen forced in 1080p, scaling 100%, signing out of windows, then signing back), everything seems to be working fine.
Now, back to 4K (3840*2160), scaling 200% (the way I ran all the tests you saw), i discovered another tiny issue:
When in the scenario selection screen, the scenario title is a bit too big, and is even hiding a few pixels of the words "difficulty" and "complexity". As you can guess, no biggie, but wanted to let you know anyway, while you are working on this !
As usual, small video to show you:
All the best !
Thanks again, I'll take a look at it!
