Short description of error
viewport render (shift-z) seams going on even if preview samples are reached

Exact steps for others to reproduce the error
with the attached file

  • start the viewport render (shift-z) on the left window (border camera view)
  • simply switch from solid to wire mode (many times) on the right window (perspective view)
  • see rendering still going on even if preview samples are reached (as show on png)

Event Timeline

Brecht Van Lommel (brecht) triaged this task as Confirmed, Medium priority.

It's not actually rendering more samples, but indeed the Time keeps increasing for some reason.

I believe this issue was introduced in D2214, where a change was made to compute the time elapsed in Progress::get_time, which means every time it is requested for drawing. Previously it would be computed when updating e.g. the status, so when actual changes were happening.
