Bug ID: 122161
Summary: UI: Bright screen flashing when starting Impress
presentation
Product: LibreOffice
Version: 6.1.3.2 release
Hardware: All
OS: Linux (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Impress
Assignee: libreoffice-bugs@lists.freedesktop.org
Reporter: g...@gmx.net
Description:
When starting prestentation, the Presentation display flashes with a bright
color (it is the window background color defined in the gtk theme).
Using a dark gtk theme, it flashes with a dark color.
The duration is longer, if the first slide is more complex (big picture for
example).
It looks little nonprofessional.
Tested with Manjaro (Xfce), openSUSE Leap (KDE), Fedora (Gnome): always the
same.
I've made a workaround for this. It works good with disabled Presenter Console
(there is another Bug). May be there are side effects for other gtk
applications.
create a new file: ~/.config/gtk-3.0/gtk.css
/* avoid bright flickering when starting presentation with LibreOffice Impress
*/
window.background.fullscreen {
background-color: #000000;
}
Steps to Reproduce:
1. Use bright desktop theme (specialy for gtk)
2. Create new Impress presentation with a big picture on the first slide (>4MP)
3. start presentation (F5)
Actual Results:
Screen flashes white, then black and then it shows the slide.
Expected Results:
Screen shows the slide (without flickering / flashing) when start presentation.
Custom color (Options -> Application Colors) would be great.
Reproducible: Always
User Profile Reset: No
OpenGL enabled: Yes
