Fractional Scaling issue
The right part of the external screen shows a black bar when using fractional scaling. This started happening this week.
Somebody else is also experiencing this problem:
Attached monitors:
- External 4K
- Laptop: qhd
Tried connection types:
- HDMI (30hz),
- HDMI over usb-c
- DP over usb-c
Fractional scaling was set up in this way:
gsettings set org.gnome.mutter experimental-features "['x11-randr-fractional-scaling']"
It doesn't seem to be monitor related. It works when:
- using wayland
- turning off fractional scaling
- during boot and login
Installed software:
- ubuntu 19.04
- Gnome 3.32.1
