I use 1.5× scaling in Sway, and haven’t observed even the slightest problem in any Wayland app. (I also use the high-DPI patches for XWayland, and run it at 3×, so that it’s an integer multiple of my scaling factor, a minor visual improvement on the very few X11 things I use that is probably not worth it.) I will note, however, that Firefox is rendering content at 2× and downscaling; setting the experimental widget.wayland.fractional_buffer_scale to 1.5 distinctly improves rendering, but had some very annoying bugs when I tried it several months ago which became debilitating maybe a couple of months ago, so I gave up on it.
- minimaul 5y agoThe one that sticks in my memory the most was a bunch of issues with Qt-based apps in particular where UI would scale in 1x, 2x, 3x steps, but font size would scale with the fractional size specified. Led to some pretty broken looking UI.
- chrismorgan 5y agoI have a few Qt apps and haven’t observed anything like this; most likely that’s been fixed. I’ve been using Wayland since April. (One thing that is comically broken about Sway and I think Wayland in general is cursor sizes. Specifying `seat seat0 xcursor_theme Adwaita 96` nets me at least four or I think five different cursor sizes, varying by app, and at least one of the dodgy sizes is actually a fractional scaling bug, scaling by ceil(1.5) rather than 1.5.)
