Created attachment 129132 [details] Affected canvas I updated to the latest version of Krita Plus, (Hash 428be56) And the canvas is entirely inoperable on my Cintiq. It works fine on my main screen, but the second it's dragged to my 4k one, it breaks. Attached is what it looks like. The bottom left quadrant is the actual canvas, but the rest of the canvas is unusable.
Can you please attach the contents of Help->System Information for Bug Reports?
This is about the same as what I got when testing out the MSIX test build (which is commit 8130dce). Likely caused by some mishandling of high-dpi (devicePixelRatio != 1) but I didn't dig any deeper.
I can partially reproduce this bug on Yoga device. I don't have artifacts like on the screenshot, but the canvas in not operable and is painted with huge offset to the bottom-left
Okay, setting the renderer to Angle makes the bug fully reproducible
FIXED: on master @ 9e9bfce29b68f87e25863ebcdf285a4c1dfe1120 Fixed OpenGL canvas rendering for High-DPI displays.
