I can't reproduce this, what settings are you using in spektakle ?

Rectangular region shot is also affected by some sort of a remanence from previous shots, yay!

What settings do you want me to use?

Well there is a delay setting, which could result in what you are describing?

I've tested that out. There you go.

All 4 were taken with these settings:

I've shot the same thing a number of times but if at 9:34 I had shot something else, the screenshot at 093740 would likely be that something else.

BUT it happens with other settings as well. If you want me to test with different settings, please post those.

This is not user error in any way. In Neon, this is not happening to me. Same machine.

Create a new user account to replicate any issues

Will do asap.

User account created. What should I do next?

Test it the same way you did on your other account, but on the new account.

Will do.

Still waiting for that test.

I'm testing others as well. As soon as I can.
