Comment 0 for bug 1825625

Setting the framebuffer scaling (with gsettings set org.gnome.mutter experimental-features "['scale-monitor-framebuffer']") allows the display on HiDPi to be scaled to something different than 100%/200%/300%.

Which would be fine.

However, the display is rendered such that most applications provide blurred display of text and graphics.

This is not always the case (e.g. system settings are displayed correctly, Thunderbird and Firefox are blurred).

Also the screen flickers when selection menus or resizing the windows.
A black border appears around the windows where the shadow should appear. It gets removed a few seconds later but still is irritating.

This issue is not urgent, just annoying. It can be worked around by removing the settings in gsetting / dconf.
