Paraview 5.7.x -> 5.8.0-RC2 - Memory leak when saving animations (png images)
It looks like memory is not freed after each frame when generating png animations (from 2D xdmf/hdf5 time dependent data [generated with FEniCS 2019.1.0]). The memory usage grows linearly with time (frame) until the Paraview process is killed. This is on an AMD workstation with 128 GB RAM (running Gentoo Linux). The xdmf/h5 file contains 15000 snapshots and memory is exhausted after roughly 9000 frames. Image resolution for this test was 1646x1306. And, I have seen this behavior for ParaView 5.6.x too.
