SUMMARY
100% (pixel perfect) view on HiDPI screens (system with fractional scaling).
After the 21.08.0 update:
100% zoom is not pixel perfect on systems with 125% fractional scaling. You can
see it in gwenview with opened image with grid.
80% and 125% not pixel perfect too.
STEPS TO REPRODUCE
1. Set the 125% fractional scaling in the display settings.
2. Open image in Gwenview (better image with grid or something).
3. See that grid lines have different widths, but they are not.
OBSERVED RESULT
Not pixel perfect view, different widths of the grid lines.
EXPECTED RESULT
Pixel perfect view, equal widths of the grid lines.
