Can you check if for example LV2 Calf, say Calf Organ's
UI can be opened or crashes?
I'm getting a crash at line 1402 in lv2host.cpp:
LV2Synth::lv2ui_ShowNativeGui (...)
{
...
HERE: ewWin = QWidget::createWindowContainer(x11QtWindow);
...
}
I recompiled our lv2GtkHelper library but same thing.
I built Calf from source and verified that MusE was opening
my installed Calf version in /usr/local but same thing.
I had suspected it was similar to the Qt4 / Qt5 difference thingy
which causes synthv1(qt4) and friends' UIs to crash upon dlopen(),
where the plugin was built with Qt4 and your system is running Qt5,
except here it would be caused by a Gtk-2 / Gtk-3 difference.
But no, it does not seem to be the same type of issue here,
it is not crashing at dlopen().
The code seems to be the correct way from what I have researched.
I tried passing a parent to createWindowContainer(),
and passing some flags as I saw suggested.
Calf was definitely working before I distro upgraded.
I will try to fire up the old distro but thought I would ask here.
Thanks.
Tim.
