We're going to need more than those patches, the problem with armhf
builds come from the osgQt that pulls in Qt's OpenGL headers that sets
the wrong typedefs. This happens for Qt4 and Qt5 and over all previous
and current releases of Debian and Ubuntu. Qt wants to create
conflicting typedefs that GL (Mesa) already sets. I'm still looking
into this to see if there is a workaround.

In addition to this, OSG-3.4 has a severe stuttering problem that was
patched in master. [1] I sent the patch to Alberto earlier but we
decided to not include it and wait for OSG-3.6 itself. Now that
OSG-3.4 is released however, we should include it (attached) ASAP.

Cheers,
Bret
