If latency is a real problem for you, buy a monitor with higher refresh rate. That’s the only meaningful way to decrease latency on modern software. Mind you, literally every single program you use will double buffer, unless you are using XMotif or so exclusively.

I actually do use a lot of XT/Motif apps. Mostly because of the lower latency but also they weren't infected with whatever brain damage generated the gtk3 design language.
