the problem for me is having mixed dpi monitors and fractionql scaling. for laptop monitor 150% to work it scales everything 2x, that also means that my external 27" 2560 which should be 1x is rendered to 5120 and that is causing stuttering and lag, at least i think it is, tried different drivers and so on. if i set the external monitor to 125 scaling then the rendered resolution is 4k and that works better, ni shuttering and lag.
i dont know why it does need to run the external monitor to 2x if i want 1x. and i lost way to much time playing with the setup. ubuntu 1904, if you have any new ideas im willing to try it.

For proper mixed dpi under Linux, you must use Wayland. But then, under Wayland, the fractional scaling is still not done (the wayland apps will work fine at given fractional scale, but x11 app will be @1 upsampled, i.e. blurry. That includes the browsers).
