Hello everyone,
I'm using Gnome 3.22 with Wayland 1.12.0 on a Dell Inspiron 15 7000 series with touchscreen.
The touchscreen works fine for the most part. However, window title bars of non GTK3 applications don't seem to respond to touch events (while title bars of GTK3 applications do). For instance, I can use my finger to drag gnome-terminal around the screen, and I can tap on the (x) button to close it. But when I try to do the same to Firefox or GIMP windows (both GTK2 apps), nothing happens.
Any ideas about this? I can't find anything relevant online.

I'm guessing your GTK3 applications are Wayland clients while the non-gtk3 applications are X clients (through xWayland)? Can you confirm this?

harshad1: Yes, that's correct. I tested them all with lg.

You only mention your touchscreen, Do you have this problem/inconsistency when you use your touchpad?

bulletmark: No. Everything else works as expected.

It appears that this is a Wayland related bug. When using the X11 backend, all applications can be moved via touch.
I think that this should be filed upstream on the Gnome Bugzilla.

OK, I reported it: https://bugzilla.gnome.org/show_bug.cgi?id=774947
