Can verify that this issue has resolved it self for me after the upgrade of these components:
gnome -> 3.28.1 mesa -> 18.0.3 linux -> 4.16.9 xorg -> 1.20
Might have been the mesa update but could be the combination of them? I don't know...
What distro are you using? I'm experiencing this on gnome 3.28.1, mesa 18.0.3, linux 4.16.5, xorg 1.19 (all from Debian/testing). Could this be an xorg issue?
