Hi list. Requesting verification of a bug: After upgrading from *buntu 14.04 LTS to 16.x, the LV2 Gtk2 UIs such as Calf and others crash upon opening them in both Qt5 QTractor and Qt5 MusE-3, at these similar calls: QTractor: In qtractorLv2Plugin.cpp QWidget *pQtContainer = QWidget::createWindowContainer(pQtWindow, pQtWidget); MusE: In lv2host.cpp: ewWin = QWidget::createWindowContainer(x11QtWindow); The crash ultimately happens deep inside the Qt5 libraries at the same place in both apps : QXcbWindow::setParent() I tried building Calf from source release, and tried different video cards. NG. But... If I bypass createWindowContainer() in MusE the UIs open and work fine! (Just that now of course they are outside of the container window.) It's Qt 5.5.1 I read about a bug fix and revert where they assumed always a valid screen but then had to revert, but that's supposed to be fixed now. I'm confused. Is it just me getting these crashes?
on my boxes, all openSUSE Tumbleweed 20160422, qtractor 0.7.7, Qt 5.5.1, i often get sth like this on most Calf LV2UI::Gtk2UI's window closing, eg:
QXcbConnection: XCB error: 3 (BadWindow), sequence: 2500, resource id: 111149141, major code: 7 (ReparentWindow), minor code: 0
but NO crashes to date, yet :) byee -- rncbc aka. Rui Nuno Capela _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
