Thank you for taking the time to report this bug and helping to make Ubuntu better. It seems that your bug report is not filed about a specific source package though, rather it is just filed against Ubuntu in general. It is important that bug reports be filed about source packages so that people interested in the package can find the bugs about it. You can find some hints about determining what package your bug might be about at https://wiki.ubuntu.com/Bugs/FindRightPackage. You might also ask for help in the #ubuntu-bugs irc channel on Freenode.

To change the source package that this bug is filed about visit https://bugs.launchpad.net/ubuntu/+bug/1767162/+editstatus and add the package name in the text box next to the word Package.

It's not specific to rhythmbox, reassigning to gtk but it might be freetype or something else in the stack. Could you add your journalctl log just after seeing the issue?
What videocard/driver do you use? Do you get the problem at random time or maybe sometime after suspend/resume for example?
