I can confirm this bug is an upstream bug. I moved from Ubuntu to Fedora for this reason but it's still present even on the latest Fedora 30 with kernel 5.0.17. Gnome shell (xorg or wayland) freezes mostly when using Chrome, I can't get Sys info during the freeze because keyboard and mouse aren't responding. No issues on KDE Plasma desktop. Tested on my work laptop (above 8 hours daily activity), Gnome freezes 4/5 times a day.
