When such a remote application window has focus, it prevents me from opening most pop-up plasmoids on my local machine. The plasmoids flicker and then disappear. STEPS TO REPRODUCE 1. Use X2Go to launch a single application remotely. 2. Give the remote application focus (for example, by Alt-Tabbing to it or clicking on it). 3. Do some action that causes a local plasmoid window to pop up. For example, click on the Application Launcher to try to show the application list, or click on the Digital Clock to try to show the calendar, or click on a group entry in the Task Manager to try to show the list of windows, or press Alt+F2 to try to bring up KRunner. OBSERVED RESULT 4. The popup window appears for a few milliseconds and then disappears. EXPECTED RESULT 4. The popup window should appear and then persist. SOFTWARE/OS VERSIONS KDE Plasma Version: 5.12.8 KDE Frameworks Version: 5.45.0 Qt Version: 5.9.4 OS: openSUSE Leap 15.0 x2goclient: 4.1.1.1 x2goserver: 4.1.0.4 ADDITIONAL INFORMATION The video at shows the bug. It shows a portion of my Plasma panel that includes the Application Launcher, the Pager, and part of the Task Manager. Claws Mail is running remotely via X2Go and one of its composer windows has focus. I am clicking repeatedly on the Application Launcher. You can see the pop-up window briefly flickering and disappearing. As far as I can tell, the problem happens only when an application run via X2Go has focus. The problem is not reproducible with applications run remotely via plain SSH. Not sure if this is a KDE/Plasma problem or an X2Go problem, so I have reported this also on the KDE Bugzilla: --Sig_/KnwS/CaZX43Kd/./tz_iLDj Content-Type: application/pgp-signature Content-Description: OpenPGP digital signature -----BEGIN PGP SIGNATURE----- iQIzBAEBCgAdFiEE2WFch0UdorzrkBIENu7AW7+KLuQFAlzBeIsACgkQNu7AW7+K LuQ6Kg/+NIGZ3/lHaheIih03KY1xMnvck8D42NzUmQ3nuw8WTIMaf97wUrQMIySs ylju8OI2BrBx48L0QIVnz2D8Z4h3EsO0LIj3Qxnl9H1QGx+br+6sVlDTJRXgKwM7 UR7yjqJkqI7y4pMYPFIInZm2I3JPa8rj4J3ps6Snk0n8esUZSF0GeH2/7ee01ENY bKo3g34Eh+oXG0kymckhHgyalEW7BAWjFYBJ0NNIFEWmvp9zq6CJIA/m8B07q8qG bFSnK06wIeLXn5pkxrvO1ENo3Qlbux7gPVKT3AOHySoibv7xWUcC6SAE/nqXRmWQ ry7KEi2RE/HDqtykCyV5jWmxdYXAqSrJlA0eC6SjN4WzjNdSazbxfp0swSjN7G9q OXV6O10HsbAfOfrRo56KXANiC6j3D9gvV7BuY/59vqLjaaEXxB1zhE9VcnSN6Q82 aXC2Bt6MW5yUwi1P2whNAbCb+R+2qBujJbVPJoRQqDS2ItrkUJ4lDyo22qt0zqIW cmJH/tXtGfZRFkdpsawGwOC6NpCqgL9L/KGfW9ee4XpwukdzEhFQtkQwvX+m6m2E 5/QMTeLwSY9BAv6bUwybW8rrKR2yujwOGPjbYFuuppe58qFh8w7UMiZkgZ+AJG22 neIeGpbBrsVfZMQqnm5yXG/9l/xHodAuXkRO2NUvLOEdhSGsjq0= =NnWg -----END PGP SIGNATURE----- --Sig_/KnwS/CaZX43Kd/./tz_iLDj--
