Hi Mike,
At first please add this issue & solution in Qt 5.12.8 known issues page
(https://wiki.qt.io/Qt_5.12.8_Known_Issues)
And yes, this issue will be fixed in Qt 5.12.9 but I don't think this is
critical enough to cause immediate release; users who are affecting can still
use previous Qt 5
Hi
we just noticed that, as now reported inQTBUG-83486,
a recent patch to Qt 3D [1] has broken all applications that
use Scene3D and non-default aspects (in particular the often
required animation aspect).
This is now fixed in [2]
Would it be possible to bring forward the release of 5.12
