Window screenshot failing

SUMMARY

In the plasma beta 5.26.90 Spectacle often only captures a partial window when capturing Active Window or Window Under Cursor.


STEPS TO REPRODUCE
1. Open Spectacle and take a screenshot from a window

OBSERVED RESULT

Often (not always) only a partial part of the window is captured. See attached example video.

EXPECTED RESULT

The full window should be captured.

ADDITIONAL INFORMATION

This happens on a multi display setup:

- Left: Unscaled - shows no issue
- Middle: Scaled - with this issue
- Right: Unscaled with this issue 

Setting the Middle display to Unscaled (100%) seems to fix the issue on Middle and Right.

It looks like the scaled display throws off some coordination calculation - but only sometimes?
