Reported to emacs bug tracking system as https://debbugs.gnu.org/cgi/bugreport.cgi?bug=30653
This is likely a bug in X11 or a driver, not in emacs.
From https://bugs.freedesktop.org/show_bug.cgi?id=105135 "This is fixed in mesa 17.3.6, which was just released to address this specific bug."
To get the fix do (for now) sudo dnf --enablerepo=updates-testing update 'mesa*' and restart X11 (or reboot).
