Strange behaviour in Monterey. strobing screen snap shot.

[Nurgle2024]

Hi, I take loads of screen shots all the time. especially when I get error messages, from web sites or programs etc.

but this is the first time I have had this happen.

the screen shot of an error dialog box from On1 installation had an error message that I needed to look up.

but it keep high speed strobing between grey & blank, snap below does not really show the strobe. will try and make a movie...

Not a great problem at all, but highly unusual. first time in all my decades of Mac computing.

regards, Sandy

Hello,

Not something I have seen either. A video would definitely help diagnose the issue.

hi, I moved that strobing icon to a storage folder, and now it won't strobe. so it must have 'fixed' itself in the moving. regards, Sandy
