           Summary: [wayland] Spectacle Rectangle Select has Inaccurate
                    Sizing on Multi-Screen Multi-Scale Configurations
    Classification: Applications
           Product: Spectacle
           Version: 24.02.0
          Platform: Other
                OS: Linux
            Status: REPORTED
          Severity: normal

SUMMARY
When Spectacle's Rectangle Select is activated, selecting a region will show
the sizing in a box above or below the region select. However, this sizing is
very inaccurate. Selecting a window on a 1080p screen will show it as being
larger than the actual resolution of the screen. Selecting close to the whole
1080p screen will actually display a value approaching 3840x2160 (give or take
10-15 pixels), which is the resolution of my scaled display.

On the scaled display, single, small windows can exceed measurements of 5,000
pixels in width and 3,000 pixels in height, which is of course not correct.

Even if the displayed resolution is incorrect, screenshots saved on the scaled
display are actually correct (i.e. instead of displaying 5,000 pixels, it will
only be 2,000 pixels when saved).

However this is NOT the case for screenshots on the non-scaled displays; the
incorrect value Spectacle shows is the actual resolution the files are saved as
- This issue is probably the same as Bug 478426.

STEPS TO REPRODUCE
1. Activate region select with Spectacle
2. Select a region
3. Size is not accurate


OBSERVED RESULT
The resolution preview for Spectacle Rectangle Select is inaccurate.


EXPECTED RESULT
The resolution preview for Spectacle Rectangle Select should be accurate,
reflecting the actual window sizes.


SOFTWARE/OS VERSIONS
