Public bug reported: I'm not sure this is specifically the ubuntu-ui-toolkit, but if I use a Label vs Text seems to affect the number of windows I can open so thought I'd check here first.
What happened: 1) Branch the demo-app [0] 2) Launch the app 3) Notice a window appears with a number 4) Click anywhere in the window to launch another window with an incremented number 5) Keep clicking on the first window, generating a large number of windows 6) Notice at a certain number as the window is spawning all the other windows close. For me this happens at different times depending on the environment/app, if I change the Label inside the Window to Text it happens later, or if I switch from the LXD/LXC based SDK to running $ qmlscene directly on the host this also increases the number of windows I can generate. ------|-Label-|-Text-| LXD---|---61--|--81--| Host--|--125--|--143-| What I expected to happen: For me to be able to keep generating a number of windows without other windows being closed. Note: When I found this issue in a more complex app, the lowest limit was 14 not 61 windows, so the complexity of the app may affect this. 0 - https://code.launchpad.net/~ahayzen/+junk/multi-window-issue Environment: Unity7, 16.04, with stable overlay PPA. $ apt-cache policy qtdeclarative5-ubuntu-ui-toolkit-plugin ubuntu-sdk-ide qtdeclarative5-ubuntu-ui-toolkit-plugin: Installed: 1.3.2085+16.04.20160916 Candidate: 1.3.2085+16.04.20160916 Version table: *** 1.3.2085+16.04.20160916 100 100 /var/lib/dpkg/status 1.3.2085+16.04.20160915 500 500 http://ppa.launchpad.net/ci-train-ppa-service/stable-phone-overlay/ubuntu xenial/main amd64 Packages 1.3.1918+16.04.20160404-0ubuntu1 500 500 http://gb.archive.ubuntu.com/ubuntu xenial/main amd64 Packages ubuntu-sdk-ide: Installed: 4.1.0~161+201609151241~ubuntu16.04.1 Candidate: 4.1.0~161+201609151241~ubuntu16.04.1 Version table: *** 4.1.0~161+201609151241~ubuntu16.04.1 500 500 http://ppa.launchpad.net/ubuntu-sdk-team/ppa/ubuntu xenial/main amd64 Packages 100 /var/lib/dpkg/status $ lsb_release -rd Description: Ubuntu 16.04.1 LTS Release: 16.04 $ lspci | grep VGA 00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09 ** Affects: ubuntu-ui-toolkit (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu SDK bug tracking, which is subscribed to ubuntu-ui-toolkit in Ubuntu. https://bugs.launchpad.net/bugs/1627105 Title: Opening a certain number of windows closes already open windows Status in ubuntu-ui-toolkit package in Ubuntu: New Bug description: I'm not sure this is specifically the ubuntu-ui-toolkit, but if I use a Label vs Text seems to affect the number of windows I can open so thought I'd check here first.
