It is laptop. Video card: Intel Corporation HD Graphics 620. Os: Arch Linux (with latest Qt 5.12.2 from repo), VTK from sources (https://vtk.org/download/).
Reboot doesn’t help at all, problem never disappear.
When software rendering in opengl is enabled (LIBGL_ALWAYS_SOFTWARE=1 environment variable) this problem disappear.
I noticed this problem earlier under VM (virtualbox/vmware) when forgot to enable 3d graphics acceleration under Ubuntu 18 / Centos 7.
