I am experiencing slowness on region capture. Sometimes 10 or 15 seconds or more after pressing Ctr Prn Scn.
Also, just hitting Prn Scn for full screen capture can sometime take 5 to 10 seconds or more before the capture takes place, other times it is instant.
It is a decent speed laptop, i7, 16Gb RAM, 480Gb SSD and pretty fast for everything else.
I am currently using v4.29.0
I love this program but it can be frustrating when you hit print screen, think it has captured, scroll down then the capture then kicks in an captures something else.
