SUMMARY

I understand the performance implications, but it is very annoying when I see a scaled down version of a window and it is not smooth at all.

This is actually hard to take a screenshot of but I managed to do so with OBS and mpv. Spectacle cannot do it.

STEPS TO REPRODUCE
1. Hover over icon on task manager.
2. View window preview.

OBSERVED RESULT

Preview is blocky.


EXPECTED RESULT

Preview should be scaled down with something like bicubic filtering.
