Title:
preview blank
Status in OpenShot Video Editor:
New
Bug description:
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.
