Description Fernando M. Muniz 2025-03-31 20:02:43 UTC

Spectacle is now part of KDE Plasma, which I assume it means it can better communicate with that desktop environment.

There is a small delay between the moment the PrtSc key is pressed, and the screenshot it taken.

Is it possible for KDE Plasma to save that rendered frame from the moment the button is pressed, then send it to Spectacle?

This would be useful for capture quickly fading elements. And work as a fix for Bug 495825 since what you see is what you get.

Sending to the Spectacle developers for consideration

While the UI is a bit delayed because it doesn't always load fast, the screenshot should pretty much be whatever was on the screen the moment you pressed PrintScreen. I'm not sure if it's frame perfect, but it should be as close to frame perfect as it could be at this point in time. I'm not sure if I should mark this as RESOLVED since I'm not totally sure if it's really frame perfect.

Press PrtSc while moving the cursor in circles.

Circles was hard to test, but a straight line worked. Yep, there's definitely a delay.
