Summary

0001996: Histogram / waveform monitor will refresh repeatedly even with refresh disabled. Resource hog prevents normal playback.

Description

Every session when I have a histogram or waveform monitor open whilst editing or playing clips back the scopes will start to constantly refresh, even with refresh off unticked and do so even when a clip is not playing or has finished playing.

Trying to play a clip after that is impossible, the constant refresh seems to take a lot of resources.

So I have to close the histogram or waveform panel and reopen it. I then get normal playback and the histogram stays still. For a while then it all goes wrong again and starts refreshing.

Have same problem with waveform monitor and to clarify this is with the refresh tick box unticked.

Do you change this afterwards? * Regarding the other colour scopes, are they set to «Refresh» (no matter whether shown or not)? * Are you using the SVN version? (Then you could enable some debugging options) * Shouldn't make a difference, but are you using kde or a different desktop? * Can you make out when exactly the behaviour changes? E.g. are the scopes in a stack, and does refresh start when hiding a widget and showing it again, or just randomly?
