Have you tried for instance this solution?
Just tried this and no, it did not work :/
Any fixes to this bug already? It's been 3 years and I'm still experiencing exactly the same issue on Ubuntu 18.04 running Mathematica 10.4.1
I concur. I'm currently seeing this problem on Red Hat EL 7.2 with Mathematica 10.3.1, but it has existed through several versions of Mma and RHEL. Please fix!
This problem still exists with Mathematica 10.4 on Gnome 3.18.
