[Paraview] -EXT-Re: Paraview display issue on Windows

Mon May 14 18:32:12 EDT 2018

I  suspect all these issues relate to QOpenGLWidget related changes to
ParaView. We are working on a update to rework that change, it would be
worth trying out the nightly binaries once those changes get merged in.

FYI the work is happening here:

experiencing similar issues with Qt5?

but they are either work-related (e.g., Matlab) or seemingly harmless
(e.g., steam). BTW, I don't have Nahimic sound driver, which I saw other
people reporting messing up with Qt.

could always try removing steam and seeing if ParaView versions 5.2+ work,
but that may be more than you want to do.

so that ParaView won't find Matlab's Qt instead of the Qt version ParaView
ships with. Some folks have run into this problem in the past and modifying
the PATH was the solution.

I installed the Paraview v5.5 (and nightly build of 3D Slicer) and both
suffered from the same display issue, i.e., the interface of the software
looks semi-transparent, please see attached picture (in case the picture
does not show correctly, here is the dropbox link to it:
https://www.dropbox.com/s/1bveei3gjg01svb/bbb.png?dl=0). The developer at
the 3D Slicer forum said it might be a video card driver issue and that I
might get more help here. My computer is a desktop, with only one video
card (GTX1080) and the driver version is 397.64 from the Geforce Experience
software. The operating system is Windows 10 64 bit with latest April
Update installed (I haven't tested Paraview before that...)

> It also happens on 3D slicer nightly build (05/02) (in case it does not
show correctly, here is the dropbox link to the picture:
https://www.dropbox.com/s/dqj5yh0hcj5ma7v/aaa.png?dl=0):

> BTW, when I first got Paraview v5.5 installed, it threw an OpenGL driver
error upon launching. Then I updated the video card driver to the latest
one and now the error is gone but the interface still seems
semi-transparent.....
