Problem is not with handbrake , it is something wrong with my wayland setup because other apps too(Pamac) have failed to start in wayland but work nicely in x11
On x11 there is a different issue of uniform scaling some apps respect scaling and some don’t (require hacks)
For these reason I have booted back to the dark side (Windows) and will try again when I have energy or have forgotten my misery in Linux.
