To adjust the 4k to a similar resolution as the full-hd I played a lot with randr and fractional scaling. The most stable and best looking solution I came up with: I run the 4k screen not at 4k but at a lower resolution. The screen does an upsampling. This solved many issue and foremost it reduces the rendering effort: 4k rendering and downscaling puts unnecessary pressure on your CPU/GPU. Modern screen should be easily able. My 4k run at lower resolution does not show any fragments. Furthermore I own a 13" laptop that natively runs at 1440p. Since running it at full-hd, battery lasts much longer and system hiccups got reduced a lot. A higher resolution on a 13" is a waste. The screen looks great at full-hd with upsampling. regards, ente
