Description postix 2020-04-29 09:56:51 UTC 
SUMMARY

It is not possible to take a screenshot of the grid view, when Spectacle in rectangular mode. 
Instead something weird happens.


STEPS TO REPRODUCE
1. Open spectacle, set area to "rectangular region" and delay to 5 seconds, so you have enough time to open the grid view
2. Press "Take new screenshot"

OBSERVED RESULT
A screenshot of the grid view is taken as is, allowing to select a region.

EXPECTED RESULT
Each desktop displayed becomes the before seen grid itself. Clicking somewhere goes back to the usual grid view.

Screen recording.

Edit: It's actually possible to take a screenshot of a rectangular region after clicking on one of the virtual desktops, which display a grid.

Please see the video demonstration.

At least on X11 I can still reproduce it.
