Do you know what the issues are? As far as I can tell GTK3 works fine on RHEL7 and does also fix a few niggles from GTK2.

These issues describe the same/similar problem.
Presumably you have tried these two workarounds:
By creating a new user, copying everything within ~/.config from my usual user to the new user, and then iteratively removing config files, I have found the culprit on my system:
GTK_IM_MODULE=xim
I had set this environment variable so that XCompose would work in Gtk+ applications. (The default Gtk+ input method was ignoring my ~/.XCompose file.)
If I unset GTK_IM_MODULE before starting Eclipse, the flickering problem goes away. Surprisingly, my custom compose sequences still work in Eclipse, so I guess Gtk+3 has added support for XCompose in its default input method module.
Would be great to know *why* XIM causes flicker in Eclipse, but I guess that's an exercise for the SWT developers. :)

Hi,
Just my two little cents for those who are looking for a temporary fix. Flickering disappeared by removing gtk3 setting.ini in /home/$USER/.config/gtk3/ (don't forget to login/out afterward).
yes, tried these two
I can't see any discussion in these tickets about gdm or lightdm.

However, with gtk3 there are issues on debian.
