Filters not working as intended

[sfjuocekr]

Is there an existing issue for this?

• I have searched the existing issues

Are you using any gamescope patches or a forked version of gamescope?

• The issue occurs on upstream gamescope without any modifications

Current Behavior

When I use the "linear" filter everything works fine.

When I use nearest (neighbor) or pixel filters it looks like there is some memory corruption going on!

Steps To Reproduce

Launch gamescope with:

gamescope -S integer -F pixel

I do not like linear smearing or any other upscaling beyond integer scaling with a pixel filter :(

Logging, screenshots, or anything else

It seems to happen with screen redraws/updates for windows that are not a perfect 1:1 fit, for example when I move the mouse in launchers (Battle.net/RSI/etc).
