Description Moritz Carmesin 2025-11-06 13:04:23 UTC

SUMMARY

The rectangular region tool captures a region of the screen that does not match the selected area. 


STEPS TO REPRODUCE
1.  setup 2 displays 
2.  deactivate the left display
3.  use spectacle to capture a rectangular region on the remaining (right) screen

OBSERVED RESULT

the actually captured region is taken from an area shifted to the right (probably by the width of the left, deactivated display)  w.r.t. the selected region.


EXPECTED RESULT

the captured image should correspond to the selected area
