Title: Fractional Scaling shows a black bar Status in gnome-shell package in Ubuntu: Incomplete Bug description: 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: * [ubuntu discourse post](https://discourse.ubuntu.com/t/x11-hidpi-scaling-available-for-testing-on-disco/10293/23) * [photo](https://ubuntucommunity.s3-us-east-2.amazonaws.com/original/2X/5/509069037c78c1e5b461e526236ffeb207de1025.jpg) 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 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1852864/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
