Created attachment 126561 [details] Window titlebar black, no buttons SUMMARY I have updated to KDE 5.18.2. While I am reading the web with Firefox, suddenly titlebar of the window turns totally black and no buttons exists. (screen capture included). I can't say what triggers the behaviour, but I didn't have this kind of behaviour with older KDE versions. STEPS TO REPRODUCE 1. Open Firefox 2. Browse the Internet awhile 3. Notice that titlebar has disappeared OBSERVED RESULT Window titlebar turns totally black EXPECTED RESULT Window titlebar is normal with buttons SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: Kubuntu 19.10 (available in About System) KDE Plasma Version: 5.18.2 KDE Frameworks Version: 5.67.0 Qt Version: 5.12.4 Window decoration style: air-oxygen ADDITIONAL INFORMATION This kind of behaviour happens only with Firefox.
Does it come back after a resize?
It remains same although I resize the window. It happened once also with Kontact yesterday.
OK, FYI, switching the decoration back to breeze will almost certainly fix it. But before you do: Do you know if you toggled compositing at all? Please include output of qdbus org.kde.KWin /KWin org.kde.KWin.supportInformation

Ok, Sorry for inconvience. I didn't notice the request for information. So, I ran the command and created KDE Identity and the output is available in address: https://invent.kde.org/snippets/768 This bug appears every now and then, I will run the command again when the title bar is black again.
