Is it possible to change the resolution of TeXmacs on Windows?

I’m using a 4K monitor and TeXmacs looks very well on it with high resolution, but it is a bit slow. So I wonder if it is possible to render TeXmacs with a lower resolution (I can live with slightly blurry UI) and will it improve the speed so there is no short delay when typing?

I’m asking this because I find that running TeXmacs in WSL and get the GUI using Xming improves the speed, with the side effect of slightly blurry GUI.

I’m not sure it is a resolution issue, maybe is the different library used by TeXmacs to render under Windows and under WSL. Are you using the last version of TeXMacs (1.99.21)?
