Trying to do a screen capture recording using native (shift-cmd-5) produces a mov file which saves tp the desktop alright. But when playing it back the picture is all mangled / pixelated and largely blue color (using QuickTimePlayer or Preview)
If I move the same file to macOS Catalina it plays fine. Also if I open the file in VLC it plays fine.
If I move a similar file recorded from macOS Catalina to this M1 MacOS 11.2.3 it plays fine.
There seems to have been a corruption of the Video PLAYBACK codec for specific M1 screen recordings. Since it plays back Catalina made screencaptures fine it is some weird kind of bug.
This worked last week before 11.2.3 update was introduced.
Problem with Quicktime Playback?
