this has been a problem for multiple years. its caused me not to use my monitor at 4k because i love firefox but cannot stand a white bar on the side. im over this problem, it has not been fixed in several years (3+) with any update. Edge, Chrome, and Opera do not do this, only Firefox. I have tried standard, beta, nightly, and they all do the same thing. It is a firefox problem. Not windows, gpu driver, or anything else. Scaling above 100% should be just fine. I am ready to be done with Firefox as you guys don't seem to care about the problem at all. I have seen multiple posts on here about the same problem, and nothing gets done. Please fix this problem soon. I am ready to switch back to chrome -_-

Scaling issue is usually a GPU driver or O/S setting conflict. Has this happened before? And did you try it in Safe Mode to see if that happens or not.
