performance : in movie mode, contour images and raster images are not synchronized

[kswang1029]

this is likely the performance issue. When contours are enabled and in the movie mode, the fps for the raster images is faster than the contour images. Ideally, the fps of the two should be the same (synchronized).

I think this may already be fixed. I was NOT able to reproduce the issue from my branch, but when I reverted back to the develop branch I was able to reproduce the issue.

Thanks, Susan. Anthony has helped to build your latest branch and indeed the raster and contour are synced in movie mode. :)

Oh, this issue is back alive.

Indeed, with the default "analysis" layout, raster and contour are synced (same fps). However, if we open up one or two more images (or image cubes), or if we enable the profile/histogram per channel/image_context/image_zoom, the unsynced feature comes back.

I am not able to reproduce the problem. Could you make available the images you are using as well as how you are generating the contours? Are you opening the images in the same window or different windows?

Hi Susan, sorry for the late reply...

To reproduce the issue:

1. open orion_12co_hera.fits
2. in the clipping tab, disable "recompute clips on new frame" and select 100% clip level.
3. in the colormap panel, using linear with lower and upper limits to -5 and 110, respectively
4. add a new window and select "imagecontext" and make the "link"
5. in the image settings, make 10 contours from 20 to 100, change contour color to cyan for better visualization
6. now play the movie and we should see that the raster and contour are not synced. Let the movie show ~10 channels and stop the movie.

Thank you for the reproduce details. The scenario described above should now be fixed.
