Fedora 40 based distro, some apps have rendering issues when desktop DPI to is set to 125% or 150% (but work fine at 100% or 200%). I thought it was a Gnome issue but it's actually a Wayland issue displaying legacy X11 apps with fractional scaling.
So my workaround for now is to just find apps with native Wayland support, which isn't too difficult as it's growing in popularity.
I used newpipe for a long time, currently using a fork called pipepipe. I forgot why I switched lol
