Description Eamonn Rea 2024-06-09 00:15:05 UTC 
SUMMARY
Single-Window Recordings in Spectacle have an incorrect resolution. On a 3840x2160 display @ 150% scaling, a recording of a maximised window will have a resolution of roughly 2560x1440. The width will be 2560, but the height will be slightly less, probably because of the height of the panel offsetting this.

This does not affect single-window recordings on non-scaled displays, only on scaled displays.

The Spectacle compression means this isn't a huge issue, but it is probably not ideal behaviour.

STEPS TO REPRODUCE
1. Maximise a window on a scaled display
2. Take a single-window recording
3. The resolution will be close to the scaled resolution of that display (3840 -> 2560, 2160 -> 1440).

OBSERVED RESULT
Single-window recordings are at the scaled resolution of the display and not the unscaled resolution.

EXPECTED RESULT
Single-window recordings should represent the true resolution of the window.
