Hi. 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.
This site is for the co-ordination of the Ubuntu project(s), and not support.
For Ubuntu Support options, please have a look at https://community.ubuntu.com/t/finding-help/7127
Yes many sites (eg. ask ubuntu) do not support Ubuntu 19.04 (disco) until it’s release later this week, but others (eg. irc in ubuntu+1) do support Ubuntu 19.04 now.
If it’s a bug you wish to report - please report it on launchpad.net (https://help.ubuntu.com/community/ReportingBugs)
Please report that problem as a bug by running:
ubuntu-bug mutter
Thanks for the bug report. We can close this discussion now. Further comments should all go in the bug report.
