I really hope this won't happen! Some packages can live many years without maintainer. But ParaView is too large and complex to use this opportunity. If RC-bugs will not be resolved on time - any package is being removed from the testing, and later - does not go to release.

As I said, this new feature is really appreciated, but it has the flaw of making edges (on surfaces and in wireframe representations) look weird with "blotted" intersections. Once this flaw is fixed, this new anti-aliasing feature will be great! Luckily, while reading the above-cited upstream issue, I found out that this new anti-aliasing feature is enabled by default, but it may be disabled. For those following this bug log, the procedure to disable the anti-aliasing is: • select Settings... from the Edit menu • in the "Render View" tab, uncheck "Use FXAA" Since this feature may be disabled by the user, whenever it is considered harmful, the paraview package no longer appears to be unusable. I am therefore lowering the severity of this bug report. Thanks for your help so far. -- http://www.inventati.org/frx/ There's not a second to spare! To the laboratory! . Francesco Poli .

Bug#894462: paraview: edges are blotted [regression]
Hi Francesco, thanks for bugreport. The problem with paraview now is that it does not actually have any active maintainer [1]. I am not using it any more and the Gert (thanks to him!) is doing some technical uploads. If you really want it to be fixed (as well as export to AVI), feel free to join our team and provide some patches. Or at least the communication with upstream would be very helpful. Otherwise paraview is the good candidate to be dropped from the next release.

Since I did this upload as a team upload I can give you one comment (I don't used the program myself, and I have no idea how to use it, I am only somewhat familiar with VTK, but also only from the "get it to compile" side and not so much from the "how to use it properly"). With this upload I switched the package from using the deprecated "OpenGL" redering interface (based on OpenGL 1.1) to the new "OpenGL2" rendering interface (based on openGL 3.2), which means that his might be a fallout from this rather big upstream change. These two upstream bugs might also be related: https://gitlab.kitware.com/paraview/paraview/issues/17202 https://gitlab.kitware.com/paraview/paraview/issues/16882 Best, Gert -- debian-science-maintainers mailing list debian-science-maintainers@lists.alioth.debian.org http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/debian-science-maintainers
Bug#894462: paraview: edges are blotted [regression]
Package: paraview Version: 5.4.1+dfsg4-2 Severity: grave Justification: renders package unusable Hello paraview Debian package maintainers, thanks for uploading a Debian revision that uses Qt5 rather than Qt4! I've just upgraded to it on my Debian testing box, but I found a bad regression that renders the package unusable to create beautiful and clear visualizations (this may be considered as basically the main purpose of paraview!). The attached test case is based on one of the data files generated by the little program included in the test case sent for bug #892293. The program source (written in Fortran) is included again for completeness' sake. Steps to reproduce the regression: 0) start paraview $ paraview 1) click on the "Open" button and open "wave0001.xyz" 2) specify "PLOT3D Files" in the "Open Data With..." dialog window 3) click on the "Apply" button 4) change the representation from "Outline" to "Surface With Edges" 5) from the File menu, select Save State... 6) save the state as "wave_PARAVIEW-VERSION.pvsm" 7) from the File menu, select Save Screenshot... 8) save the screenshot as "wave_PARAVIEW-VERSION.png" By performing these steps with paraview/5.4.1+dfsg3-2 and with paraview/5.4.1+dfsg4-2, I obtained the two attached screenshots. In paraview/5.4.1+dfsg4-2 there seems to be a commendable attempt to apply some antialiasing to all the lines (including the edges on surfaces, the wireframe edges, but also the lines of the orientation axes, and so forth...). Unfortunately this new feature creates unsightly images, whenever the edges are shown from a distance. Please take a look yourself at the wave_5.4.1+dfsg4-2.png screenshot: all the intersections between edges seem to be somehow "blotted" and unpleasant to look at. Please fix this regression, as it makes paraview unusable. Thanks for your time!
