Yes, an `export QT_QPA_PLATFORM=xcb` only applies for the current terminal, i.e. processes started from there. > Moreover, About Libreoffice shows "VCL:kf5(cairo+xcb)" with QT_QPA_PLATFORM > set but "VCL:kf5(cairo+wayland)" without.

Yes, that's expected. LibreOffice doesn't start a new process/"session", but reuses the existing one if it's already running. (In reply to p.wibberley from comment #9) > Oh, and "--nologo" doesn't seem to make any difference. Thanks. So to summarize: There's an "soffice.bin" window showing up temporarily when starting Writer, that then disappears and the actual Writer window shows up. This happens when either running LO as a native Wayland application (starting LO without QT_QPA_PLATFORM=xcb set) and when run with Qt's xcb platform, i.e. on XWayland (starting LO with QT_QPA_PLATFORM=xcb set). For the Wayland case, that "soffice.bin" window is shown much shorter than for the xcb case, but it's still shown. Is that correct? Could you please try whether you see the same when you start LO with environment variable SAL_USE_VCLPLUGIN=gtk3 to force the use of the so-called gtk3 VCL plugin? (Please double-check that "Help" -> "About LibreOffice" shows "VCL: gtk3" then.) -- You are receiving this mail because: You are the assignee for the bug.
