Hi, I tested the version 25.xxx and 26.xxx even 27.xxx
My setup is iMac 2019 with OS Big Sur , with addition one TV monitor and one Projector
When I put the preview to full screen to projector, The projector did fullscreen view but all the other screens turn black until I push the esc out of the preview.
I traced back the older version like 24.xxx, and it works fine. but 24.xxx had other bugs and seems run slow on Mac OS.
Anyone has any idea about this problem?
