Created attachment 140959 [details] KWin supportInformation SUMMARY Taking screenshots with Spectacle renders old content instead of what is actually on the screen. I have to "reset" Kwin by changing some Compositor settings before taking screenshots. STEPS TO REPRODUCE > Open Spectacle and take a screenshot using rectangular region. The screen changes to some old state as it was when I had just logged in, including a partially black screen and a notification widget showing "Connected to wifi". > Try "Window Under Cursor" The same thing happens. Either some old window or the desktop itself comes in the screenshot, but not the currently open windows. > Go to Compositor settings and change "Scale method" or "Rendering backend" to something else. Now Kwin resets and I can take screenshots of the current screen again. This bug appeared in the last month or so. Willing to help debug.

Well, I digged into my Arch configuration and turns out the issue was installed xf86-video-intel driver, which is not recommended [0]. Removing the driver seems to have fixed the issue. Will report back if it reappears. [0] https://community.kde.org/Plasma/5.9_Errata#Intel_GPUs
