594935d8d533cb30d7cfcc7d186dee50a54c4af1 "Split PM_CAPTURE mode into

EVR-CP: Fix a jump few frames ahead when pausing the video after seeking.

The issue was introduced in 5b803b86b2b7fe138f76e65712664e466870ce97.

A forced repaint was sometimes triggered because of a flush but the renderer was unpaused before the redraw happened and it was delayed until next time the renderer was paused.

This commit fixes #4182.
