Duplicate portion of the screen

SUMMARY
When openning the Spectacle overlay (Meta + Shift + S, or from KRunner), the top portion of the screen is duplicated and when cropping the screen the result is innacurate.

STEPS TO REPRODUCE
1. Open Spectacle
2. Notice the top portion of the screen is duplicated
3. Use the Crop functionality to grab a piece of the screen
4. Save the capture and look at it, it won't match what you selected

OBSERVED RESULT
Duplicate top portion of screen and incorrect cropping


EXPECTED RESULT
Regular screen and correct cropping


SOFTWARE/OS VERSIONS

ADDITIONAL DETAILS
I am using a dual-monitor setup with different resolutions. Behavior is observed on both monitors.

Update:

A few hours later, the problem seems to have went away. 
System hasn't even gone through a restart, only a fullscreen YouTube video and a lock/unlock.
