Public bug reported:

When I start a new project and add my video files the preview works.

Once I get to maybe 7 or 8 clips added into the timeline, it will no
longer show the preview in the preview window (it is black) but the
audio plays.

I have tried installing from apt and from source.

Once the preview stops working in the project it stops for good
regardless of reopening the same project file.
