Dear Maintainer,

When I lock my screen and turn off my monitor, after I turn it on again, the
screensaver only occupies 1/4 of the screen (the top left quarter).

You can see the other 3/4 of the screen as though the screen isn't locked.
So it's a problem if you were depending on the screen saver / locker to hide
any information there. But the whole screen is still locked and you can't
interact with it.

My screen is 4K and I'm using 200% scaling.  I tried reducing scaling to 100%
and it fixes the issue.  I also didn't have the issue in Bullseye and only
encountered it after I upgraded to Bookworm.

My video card is the integrated graphics in an AMD Ryzen 5700G (Vega).

I tagged the bug as "upstream" when reportbug asked because it seems to be an
outstanding bug there:
https://github.com/linuxmint/cinnamon-screensaver/issues/337
but it was initially reported on cinnamon-screensaver 4.4.1, but I didn't have
the issue in Bullseye which used 4.8.1.

If I can provide any other info let me know.  Thanks!

Jared
