<p><tt>Hi all,</tt></p>
<p><tt>Some folks have been running into strange rendering issues
with the Qt Render window interactor in Python, on Linux, with
transparent actors. I've reduced this to two scripts that I
attach which just require VTK-Python. The first is with pure
VTK and which seems to work fine and the second is with the
QVTKRenderWindowInteractor which fails.</tt></p>
<p><tt>The script just creates two semi-transparent spheres one next
to the other and turns on depth peeling. When the example fails,
the blue ball can never be seen in front of the red one. This
example works fine with VTK 8.1.1 on Mac OSX but fails on Linux
(ubuntu 16.04 and 18.04). The non pyqt one works just fine. I
did try experimenting with using QGLWidget and also with using
the newer QOpenGLWidget but they both display the same issue on
Linux it seems like.</tt></p>
<p><tt>Have any of you seen this before? The blog post here:
<a class="moz-txt-link-freetext" href="https://blog.kitware.com/vtk-8-0-0/">https://blog.kitware.com/vtk-8-0-0/</a> suggests there are some
transparency issues with the C++ widget as well but I am not
sure if those are already resolved. Any thoughts or pointers on
this?<br>
</tt></p>
<p><tt>Thanks!</tt></p>
