Slow animation with selections

We have a bug with the selection code. It creates huge slowdowns playing animations. Here is how to replicate:

  • 5.2.0-RC3. Mac. Local server.

  • can.exo. All vars on. Apply.

  • Play. This is how fast can.exo should play.

  • Leave at last timestep.

  • Find Data. Cells from can.ex2. EQPS >= 1.5. Run Selection Query.

  • Play. Notice how slow can.exo plays.

  • Reset Session.

  • can.exo. All vars on. Apply.

  • Play. Notice how can has slowed down! This slowdown is universal to all animation - it also now shows up when animating a sphere Start Theta!

  • I also believe that every time you add another seleciton query , ParaView slows down even more. For instance, Find Data. Global ID is max. Run Selection Query. Play

  • Again, Find Data. Global ID is min. Run Selection Query. Play.

It slows down more and more for each Selection Query.

The only cure is to close and restart ParaView.

To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
