RHEL 7.6 GNOME is buggy under Parallels Desktop 14 after Parallels Tools installation

Hi all,

I installed a RHEL 7.6 virtual machine for development purposes on my MacBook Pro 2018 15", using the GNOME desktop. However, it is really buggy after Parallels Tools installation: desktop icons are always on top of other windows, I cannot select windows using the mouse, and GNOME Shell keeps crashing. As far as I know, RHEL 7.5 works fine. Is anyone aware of any fixes for these problems?
