I have an issue on Mac OS Tahoe: whenever I lock the screen or put the Mac to sleep, all the windows resize to a small size. Very annoying. It affects all apps.
Is it a bug, or is there a way to fix it?
Thanks,
Liad
Mac Studio, macOS 26.0

Maybe showing a screen shot of your exact complication would shed some light on the problem and a resolve..
Otherwise it is a bit of guess work without knowing more...
