Did that solution involve using xrandr scaling parameter? unfortunately that's not right solution IMO, as I observed it takes lot of CPU. Hacky and feels laggy.

Did that solution involve using xrandr scaling parameter? unfortunately that's not right solution IMO, as I observed it takes lot of CPU. Hacky and feels laggy. My solution is to organize myself so that I don't have to move windows around. I mostly need browser, terminal and emacs. I open chrome in one monitor with specific scaling option, and when I move emacs or terminal around I manually decrease font size with Ctrl-+/-
