I have recently installed Ubuntu 19.04 RC. Everything works fine except the Qt applications. I have two monitors and when I pass the Qt application to the secondary monitor the characters of the application increase. They happen to the traditionally installed Qt applications and to those installed with Flatpak and Snap. I leave you a video in which you can see the problem with the VLC application. https://youtu.be/tEZJONsinU4 https://i.imgur.com/R7GubxF.png?fb To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/1824753/+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
