AMD Ryzen 7950x 64GB RAM DDR5 @ 5600mhz RTX 4090 Windows 11 AE version 24.1
I have attached a video example of this bug.
This has been bugged for at least 6-7 years, if not more. Pretty sure it happens on every Windows device. I personally had this bug happen on at least 5 different Windows devices and 2 were my own PCs with different hardware. Happens on Windows 10 and 11.
This never happens in Premire, Photoshop, Illustrator, all other Adobe apps work fine. Only After Effects goes to windowed mode and only when the project is opened from outside AE.
