Open the settings dialog, select the Display page and check whether canvas acceleration is enabled and what the scaling mode setting is.
Comment 3 monnalisa2021 2021-04-22 13:56:46 UTC
I just checked and "Canvas Graphics Acceleration" is not enabled

Then please enable it and make sure "High Quality Filtering" is selected.
Comment 5 monnalisa2021 2021-04-22 14:26:02 UTC
I enabled it, and the "Scaling Mode" options are: Bilinear filtering, Trilinear filtering and nearest neighbour, I don't see a "High Quality Filtering" option

Ok so try Trilinear, does it make it better?
Comment 7 monnalisa2021 2021-04-22 14:33:33 UTC
At first it didn't change anything, but then I closed and reopened the file and it seems to have worked!! Thank you!
