GNOME Bugzilla – Bug 589809
[performance] zooming (even without thumbnails/waveforms) is slow
Last modified: 2010-02-05 21:59:04 UTC
Zooming needs to be profiled, as zooming in/out is noticeably sluggish (try rapidly clicking on the zooming buttons or using the mousewheel). It's definitely not fluid, and makes pitivi less enjoyable to use. This is with thumbnails and waveforms turned off.
This was fixed (thanks!), don't know in which commit exactly, and I think it was in the 0.13.3 release (but I can't set that in bugzilla)
