[Qt5] QtCreator opening new project and then alt-tabing wrong title bar

[Brandon Schaefer]

An issue in qtcreator when you open a qtcreator template (ctrl+n) then alt+tab. This causes an extra white title part (that is moveable) but you cannot do anything with it. It also seems to not have a name in the window management logs.

Mir on 0.25 in yakkety

To reproduce:
1) QT_QPA_PLATFORM=ubuntumirclient /usr/bin/qtcreator on a miral-shell
2) Press ctrl+n to open a template window
3) Press alt+tab

Expected:
The main qtcreator window to be the front most window

Result:
Some window without a name becomes focused and is about half the width of main window.

I think the expectation is wrong:

[2016-09-26 15:27:14.571996] miral::Window Management: place_new_surface app_info={application=qtcreator, windows={, , Qt Creator}}, requested_specification={name=, type=dialog, top_left=(394, 272), size=(880, 520), output_id=0, state=restored, min_width=0, min_height=0, max_width=16777215, max_height=16777215, parent=Qt Creator, top_left=(394, 272)} -> {name=, type=dialog, top_left=(394, 282), size=(880, 520), output_id=0, state=restored, min_width=0, min_height=0, max_width=16777215, max_height=16777215, parent=Qt Creator, top_left=(394, 282)}

The template window dialog is modal, so the main window should not get focus on Alt-Tab,

That's what I observe. I don't see "Some window without a name". Admittedly I'm testing with lp:~alan-griffiths/miral/fix-1628033 - but if there are no other issues I'm satisfied to mark this as a dup.

Could you confirm or clarify?

That is 100% dup and what i was talking about. I just saw:

[2016-09-26 15:28:49.581234] miral::Window Management: advise_focus_gained window_info={name=, type=normal, state=restored, restore_rect=((320, 192), (640, 480)), children={0x7fd7fc003110}, min_width=0, min_height=0, max_width=16777215, max_height=16777215, width_inc=1, height_inc=1, min_aspect={0, 4294967295}, max_aspect={4294967295, 0}, preferred_orientation=15, confine_pointer=0, output_id=0}

name=,

Sounding like it didnt have a name for the focused window?
