Ubuntu app screen flutters

Im using Ubuntu 24.04.1 LTS

I used command line ‘sudo snap install invoiceninja’ and also downloaded from app store. In both instances, the window for the app flutters and sometimes makes the minimize, maximize, and close app button unusable. When i open the app on the command line, I get warnings before the apps opens…

Any tips on how to fix?

Thanks,

Hi,

I suggest trying the Flatpak version.
