only solution is to restart it
please see attached images
it happens from time to time after I open a new tab
You can try changing "chrome://flags/#tab-hover-cards" to "Disabled", or disabling hardware acceleration.
both are disabled,
the problem doesn't happen when I hover with my mouse over a tab,
the problem is that my whole page becomes smaller, much smaller,
both width and height
May be related to your Chrome theme.
Have you tried safe mode?
I'm not using a theme,
it happens randomly, after many hours of using the browser without closing,
I wouldn't want to try it in safe mode for that many hours
Based on my experience, it is probably related to hardware acceleration.
it should be,
but I've got it disabled since a long time ago
