The users may have 1080p monitors, but even Windows does not do subpixel antialiasing in its new apps (UWP/WinUI) anymore. On Linux, GTK4 does not do subpixel antialiasing anymore.
The reason is mostly that it is too hard to make it work under transformations and compositing, while higher resolution screens are a better solution for anyone who cares enough.
Is this why font rendering on my Win11 laptop looks like shit on my 1440p external monitor?
Laptop screen is 4k with 200% scaling.
Seriously the font rendering in certain areas (i.e. windows notification panel) is actually dogshit. If I turn off the 200% scaling on the laptop screen then reboot it looks correct again.
