Scopes show the same waveform for all frames in a clip
I am having trouble with the scopes in Premiere Pro CS6 on a Win 7-64 computer. For some clips the same waveforms are shown for all frames. This only occurs for a subset of clips – many are displayed correctly (including clips from the same source files as the problem clips).
Here is an example of two different frames from the same clip:
Premiere Pro displays the same waveforms for both frames:
After trying several things the only solutions I found are rendering a preview file (not optimal for color correction), or re-creating all the problem clips. I am currently in the process of replacing the clips and wanted to hear whether anyone else has experienced the same issue.

Turns out re-creating the problem clips only worked until effects were added, then the scopes froze up again. Nested sequences seem to be OK, but the approach is cumbersome.

Out of curiosity, what would happen if you take the problem clips and re-export them in some high-quality file format and bring them back into the project?
If this is only happening with some clips and not all clips of a certain type, that would point to some file defect in the specific clips to me…

Thanks for the comment. Most of the problem clips are from two mpeg files. However, not all clips from the those files have issues. In some cases there are copies of the same clip edited to different in/out points; some copies work, and others do not.
I also created uncompressed 4:4:4 intermediate files from the mpeg source files. Again, some work, others don’t.
Disabling effects applied to a clip allows all scopes to work properly. I moved the problem clips to another timeline, removed all effects, and then applied effects to the nested sequence. No issues so far.
