Select cells through in parallel does not trace correctly. Here is how to replicate: * Start with ParaView full screen. * I believe has to be in parallel. 64 ranks, Linux, 5.8.0-RC2. * Start Trace. * Open Watney's sparc-wall.exo.144.*. All vars on. Apply. * So that we have more control, letz zoom in. Adjust Camera/ Zoom In 4 times. * Surface with edges. * Select Cells Through. Now, what I want to do is select about 6 cells in the blue (cone) region, abutting against the green block. I will add a screenshot. * Extract Selection. Apply. * Stop Trace. Save as a macro. * Now, hover cells on. For me, the upper left cell is 14846. * Reset Session. * Run the macro. * Frequently, nothing shows up. Sometimes, the wrong cells show up. As I just wrote up this bug report, nothing shows up. This is a bug.
