Bug summary
Screensharing/Cast is broken when fractional scaling is enabled
Steps to reproduce
- Open Dconf-editor
- Go to /org/gnome/mutter/experimental-features
- Set value to ['scale-monitor-framebuffer']
What happened
The output is doubled, or complete black or in some kind of scanlines. Only in the cast, the actual displaypicture stays perfectly fine.
What did you expect to happen
It should just work fine.
Relevant logs, screenshots, screencasts etc.
Gnome Screensharing: (+ Boxes as client on the same system. Its the same on other systems connected to this one.
Gnome Integrated Screencast: video
This only happens if I use 'scale-monitor-framebuffer' on mutter.
