Hi,
After stopping interactive viewport, the scene gets stuck for a while, it differs from 10 seconds to several minutes. Sometimes it doesn't happen randomly. I faced this problem in several scenes and usually, it starts to happen as the scene gets heavier, but not necessarily very heavy. The problem is only at the end for interactive, the start is fast and smooth. It becomes really annoying after a while, to wait several minutes after each interactive session.
Did anyone faced similar problems? What possibly can cause this?
For info my system specs: i7 5820k, Gforce980ti, 64 gm ram
