Just posting to ask if anyone has yet found any sort of workaround for this issue?
I recently bought a 4K monitor specifically for photo editing and I find I'm having to use 200% scaling in windows control panel for it to be anywhere near usable. In other words, I haven't actually gained any resolution over my old monitor! I have tried changing font sizes in windows control panel too, but that doesn't help with the icons and it kinda puts everything out of alignment. I love Affinity Photo but I'm pretty disappointed about this, to be honest, and the fact that it's been an issue since 2016 is particularly disappointing. Maybe I'm being naive but surely it's an incredibly easy fix to implement?!
