Created attachment 146825 [details] all the background is not the windows where I am currently workig (this report for example) but an old image imposed by Spectacle. SUMMARY *** the app shows up a previous screenshot taken some time before. No matter what capture method, rectangular or full screen or the the trigger method if it is shortcut or dialog option instead of showing the current screen to capture it, the app will show an old image taken I don't know from where. I have uninstalled and reinstalled several times, it continues doing the same and showing the same image, so I suppose removing the package is not removing configuration. *** STEPS TO REPRODUCE 1. trigger a screenshot request, no matter the way 2. be dissapointed it shows some old captured image 3. try to get a region screenshot, it will do it but will capture the region of the pic it loaded itself OBSERVED RESULT EXPECTED RESULT SOFTWARE/OS VERSIONS Linux/KDE Plasma: 21.12.2 KDE Plasma Version: 5.24.1 KDE Frameworks Version: 5.91.0 Qt Version:5.15.2 kernel: 5.16.9-arch1-1 (64 bits) graphics platform: X11 ADDITIONAL INFORMATION I had to take the pic with a camera as when Spectacle is taking an screenshot it blocks other programs. There you can see all the background is not the windows where I am currently workig (this report for example) but an old image imposed by Spectacle.
I found the cause of this bug. I installed flameshot, another screenshoter and it had exactly the same problem! So I started looking for common root causes. I found here: https://forum.manjaro.org/t/spectacle-not-taking-screenshots-correctly/74466/13 that the problem was with the compositor so you have to deactivate it when taking screenshots. This workaround solves the problem for both Spectacle and Flameshot so the bug should be transferred to compositor interfering other software.
This seems to be fixed.
