As a developer I have issues using roblox on a high-resolution display.
I run Windows 10 at 4k and scale by 200% When I open Roblox Studio everything is slightly blurry. If I turn off resolution scale then the entire studio UI is far too tiny to use/see at a reasonable view distance.
This is also an issue in-game. If I see a textlabel with TextSize 10 text at 0 scaling I’ll see the same text rendered at TextSize 10, just stretched to double it’s original resolution.
