After installing Parallels tools in RHEL 7.6, I'm having issues with GDM. Applications appear in front of the desktop, but behind the icons. When I first log in, I have a blank screen with a mouse pointer for a few seconds then the icons appear, the screen goes blank and then I see the desktop rise up as usual. Abrt-Cli is reporting gnome-shell failed. I am also unable to drag applications around by their title bars, however, I can still drag them around by the blank space in the menu bar. Seems like coherence might have something to do with it. I have included a screen shot of the issue I am seeing as well as the basic abrt-cli output. Also note the only way to make an inactive application active is to use Alt+Tab. I do not know if Fedora or CentOS are affected by this or not. It is also worth noting that I have isolate linux from Mac enabled.
