Unevenly spaced desktop previews

SUMMARY
Desktop previews in the pager widget sometimes have uneven spacing when fractional scaling is used.

STEPS TO REPRODUCE
1. Set display scale to a non integral value (tested 125% and 150%)
2. Adjust panel size

OBSERVED RESULT
Sometimes desktop previews are spaced unevenly.

EXPECTED RESULT
They should have consistent spacing between them.

PS: This happens on both X11 and Wayland sessions.
Comment 2 Nick 2024-03-21 21:18:42 UTC 
Subtle, but I can duplicate this on Neon / Wayland / Intel graphics with scaling at 125% and a panel height of 38px. I think this could be a related to 483338 which relates to pixel rounding errors. Would be good to get this confirmed by a dev who knows more than me! Thanks, Nick.
