Since build 82.0.439.0 in the Canary channel, there is an odd red background in place of the black themed background when launching apps.
Please consider fixing it, it puts strain on the eyes...

Hello, consider sending comments through send feedback, so that the Microsoft Edge team sees it and can correct the bug
The problem is fixed in Version 82.0.443.0 (Official build) canary (64-bit)
btw looks like the red color was the beginning of this new feature
