Description Egor Tkachev 2025-12-02 16:48:54 UTC 
SUMMARY
I have two displays: 2560x1440@180hz with 125% scaling and 1280x1024@60hz with 100% scaling. When i do rectangular selection with spectacle it reports resolution much higher than selected area is. For example if i select ~1/4 of 2k display it reports ~2000x1300 resolution, when i select whole screen it reports ~4000x2300. Screenshot that saved or pasted into some program has normal resolution, so i think the bug is purely visual. When i switch to 100% scaling, spectacle reports correct resolution.

STEPS TO REPRODUCE
1. Set display scaling to 125%
2. Select rectangular area with spectacle
3. Check the resolution that it reports

OBSERVED RESULT
Reported resolution is wrong 

EXPECTED RESULT
Reported resolution is correct

Comment 1 Noah Davis 2026-02-05 09:17:40 UTC 
Fixed when bug 488034 was fixed, although selections that span two screens with different scales will have images that are scaled up to the next integer scale for various reasons.
