core dump
Hello Gnome developers, and thank you for your excellent work that has given us
an amazing desktop.
This is an annoying bug that causes any GTK3 application to crash when using
the touchscreen. Unless I'm mistaken, it hasn't been reported yet.
Steps to reproduce:
1. Start any GTK3 application, for instance:
$ gnome-calculator
2. Tap on the clock in the top panel, to open the calendar drop-down.
3. Now tap on the application's window.
4. The application crashes.
This is 100% reproducible on my machine. I'm running Arch Linux with Gnome 3.22
on a Dell Inspiron 15-7568.
