KDE desktop jittery windows?

I’ve just installed F42 for the first time in a long time. I ended up installing the proprietary nvidia drivers because the nouveau drivers that shipped by default don’t support suspend/resume.

I notice that my windows seem to be jittering. There’s a slow wiggle left and right, almost as if the pixels are snapping incorrectly to a display due to floating point errors.

I have a webp recording of this happening both in Firefox and in System Settings, but it happens all over the place.

What can I do to fix screen jitter? Is there a way I can upload these video files so I can share what I see?

One thing I thought to check after typing that up is the Display Configuration. By default, it appears to have set itself to 115%. Setting it to 110% seems to have eliminated the jitter. I’ll continue to monitor, because it’s mostly worked this whole time and I only thought to post this after a few days of just ignoring it.
