Pixel/Retena Mode scales incorrectly when Windows 10 DPI scaling >= 150%


Recommended Posts

I wasn't sure if this was normal or if it was something on my machine causing it, but this issue is present in V1 & V2 beta. Pixel mode displays jaggies and does not represent 100%. PNG Export looks the way it should.

I attached a recording trying out different DPI+zoom combos to show the results. I suspect it may be helpful for determining the cause. FYI: The issue is present in Publisher Designer Persona as well.

Video has sound.

Changed from NVIDIA 3080 to AMD 5600XT and can confirm this issue still happens.

The only difference is Retena does "jag out" @ 300% at 150% DPI scale in Windows 10, whereas with the 3080 it would not occur until 500%. However, it is smooth again @ 400%, and then jaggy again @ 500%.... it doesn't draw consistently with zoom levels until >= 500%...

Everything behaves as expected when Windows 10 DPI is 100%/125%.
