The size of preview-generated images (figures, formulas, sections) is
larger than normal and images are blurry when fractional scaling is used
in the desktop environment (Gnome 49.1/Wayland).
For the integer scale of 200% the size of images is normal, however,
images look blurry due to insufficient resolution.
This seems the correlate with the monitor geometry and scale factor
returned by (frame-monitor-attributes).
Actual monitor resolution is 1920x1080.
Scaling => monitor attributes
200% => (geometry 0 0 1920 1080) (workarea 0 0 1920 1080) (mm-size
530 300) (scale-factor . 2.0)
166% => (geometry 0 0 2304 1296) (workarea 0 0 2304 1296) (mm-size
530 300) (scale-factor . 2.0)
150% => (geometry 0 0 2560 1440) (workarea 0 0 2560 1440) (mm-size
530 300) (scale-factor . 2.0)
133% => (geometry 0 0 2880 1620) (workarea 0 0 2880 1620) (mm-size
530 300) (scale-factor . 2.0)
125% => (geometry 0 0 3072 1728) (workarea 0 0 3072 1728) (mm-size
530 300) (scale-factor . 2.0)
100% => (geometry 0 0 1920 1080) (workarea 0 0 1920 1080) (mm-size
530 300) (scale-factor . 1.0)
