SUMMARY In some situations, alt tab does not go to the last window used, but instead goes to some window used before that. I often experience that alt-tab doesn't go to the right window, but this one is easily reproducible so it should help fix the underlying issue STEPS TO REPRODUCE 1. Open some window (for example dolphin) 2. Open youtube in firefox 3. Start a video 4. Start gnucash 5. Quickly press f to fullscreen firefox 6. Wait for gnucash to start 7. Press f again to exit full screen 8. Press alt+tab OBSERVED RESULT When exiting full screen you see the gnucash window, which is fine. But if you press alt-tab, you go to the dolphin window, while it's not the most recently used window. EXPECTED RESULT Either one of these is fine 1. alt-tab should go back to firefox 2. when exiting the fullscreen video you should see the firefox window. Alt-tab should go to the gnucash window.

I tried reproducing in wayland, but cannot reproduce it there. Instead the gnucash window goes on top after starting and alt-tabbing goes back to the video window. This not the unexpected alt-tab behavior as in the report. I'm not sure if it's still reproducible in X11, since I don't use it anymore. Feel free to close the bug report.
