Comment 26 for bug 1838919

I upgraded both my Ubuntu Desktop and UbuntuStudio systems to 19.10 Eoan (with gnome mostly at 3.34). The symptoms have not changed... my desktop still hangs, loses keyboard events, and the log fills with the GTK 2/3 conflict messages. Meanwhile my Studio system behaves perfectly!

The log messages are generated by nautilis, gnome terminal, thunderbird, and several other applications, but I do not think they are the culprits - just the victims of something unseen.

The Studio system also has many GTK2 packages installed alongside the GTK3 ones, so there isn't a simple explanation for the difference in behaviour. I will do a side-by-side comparison of installed packages to see if there is some sort of clue.

Meanwhile, I would be grateful if anyone could suggest how to identify the guilty component. I would love to purge it!
