Some GTK windows lose interaction

[Alan Griffiths]

Easiest example:

$ GDK_BACKEND=mir mir_demo_server --launch gnome-mahjongg

Show the "Scores" - you can switch focus between this and the main window with Alt+` but doesn't respond to input.

I've not yet investigated what's unusual about this window. Some other dialogs (e.g. "About") work fine.

Also relevent to focus handling, despite being able to set focus to the main window it doesn't respond to input - with the "About" option above, closing that window enables it. With the "Scores" example it isn't possible to close the unresponsive window.

Looks as though the toolkit stops responding to input events - they are being received by the client process.

Sounds like bug 1474132

[Alan Griffiths (alan-griffiths)]

It doesn't sound similar to me. This is about input when both windows exist, lp:1474132 is about focus change when a child is closed.

I can confirm the latter does still happen when closing the "About" window described above, but this bug is about the "Scores" window not working.

Maybe bug 1445543 too.

[Daniel van Vugt (vanvugt)]

Sorry, I should have pointed to bug 1445543 instead.

[Alan Griffiths (alan-griffiths)]

It might be a specific case of lp:1445543 though.

[Alan Griffiths (alan-griffiths)]

MIR_CLIENT_INPUT_RECEIVER_REPORT=log shows the input events being correctly received on the client side.

[Daniel van Vugt (vanvugt)]

Your test case of showing "Scores" makes it a multi-window GTK app. So I think you will find this is bug 1445543.
