It seems that you are using KDE, so your windowing manager is kwin. Is that right? If yes, you can try to start systemsettings5 and go to "Display and Monitor" -> "Compositor" and try to switch the "Rendering backend" to another option. Then test if it still happens. -- You are receiving this mail because: You are on the CC list for the bug.

Xfce installed and run. Seemed fine but the problem did still show up. Back to KDE I altered just about everything in the KDE windows management, defaulting to 'doing little or nothing'. it has improved but not gone away.

I shall now go back over the alterations to the KDE settings and see if I can recreate it, if not I will report that here and, at least as far as I am concerned, that will be the end of the problem. Thank you for your succinct support. -- You are receiving this mail because: You are on the CC list for the bug.
