<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/"
moz-do-not-send="true">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>
