--- Comment #9 from poma <pomidorabelis...@gmail.com> --- (In reply to andrew p. from comment #7) > Some clarifications: > - Greeter is usual GTK3 application. > - No WM or compositor run in greeter session. > - Greeter creates one GtkWindow for each monitor. > - Greeter uses standard cairo functions to draw monitor's window background. > > There are no "login" or "panel" windows - just child widgets inside > fullscreen window. > This grey color looks like default window color - just set > "background=#default" to see it. > So, the question - why gtk draw semi-transparent panel correctly (using > parent window background as base) and do not do it for "free" space. > > Add "allow-debugging=true" option to lightdm-gtk-greeter.conf to get more > informative log. > > Some questions: > 1. What happened if background is color (#0f0)? I don't expect that there > will be any difference, just interesting. > 2. Another gtk theme? Or empty "theme-name=". > Color codes work OK, theme also does not affect the final outcome. background color (#0f0) - green, works OK as any other. > I saw very similar bug some time ago - laptop with archlinux and catalyst. > In some cases gtk didn't draw whole windows except some widgets (text > entries - blinking cursor). But this bug is gone now. Thanks for answering. -- You are receiving this mail because: You are the assignee for the bug.
