Dorico 4 resizes window over multiple screens when note color changed

When changing opacity of an item, entire Dorico window resizes to single monitor height.
It was not the case with Dorico 3.5. Any idea why this happens? Thanks

I’ve not heard of this problem before. Can you record a screen capture showing what you’re seeing, and share it here?

Hi Daniel, thanks - video attached - it seems this is happening particularly when changing color properties, not the other parameters

That’s a very unusual display configuration you have there! I’m not sure what’s going on there, but I will try to reproduce this when I am next in our office with access to multiple displays.

This is MacPro with 4 screens, worked great with previsou versions of Dorico

Althought I’m running OS 10.14.6

Dear Daniel, I’m wondering if you were able to reroduce this screen behaviour - I believe this may be a bug of working on multiple screens (even two of them). thanks -m

I’ve not had a chance to try this yet, I’m afraid.
