Summary0000605: Kdenlive takes 50% of the CPU when idle
DescriptionKdenlive 0.7.1 takes about 50% of my CPU when idle. This however is true only if the application window is active. Switching to another application reduces CPU usage to 0% (well, almost). This happens right after Kdenlive is started with no project loaded. I didn't have this problem with Kdenlive 0.6. I don't have it with other KDE4 applications either (tested with KAddressBook and KSnapshot).
Steps To ReproduceStart Kdenlive and watch CPU usage. Switch to another application to see it dropping.
Additional InformationMy laptop is a 2GHz Intel Pentium M with 2GB of RAM and ATI Mobility Radeon 9700 (fglrx).

It was reported before in the forum (although I haven't seen it when I was reporting this bug).

The only difference is that I don't have "blinking letters" effect. However the problem indeed disappears after importing a clip and dragging it to the timeline.

I have more or less the same problem here using this version of Kdenlive from Debian Unstable. Howver, I do have the blinking underline and dragging a clip into the timeline doesn't reduce the load Kdenlive places on on Xorg.

Just opening Kdenlive and bringing the window into focus with mouse-focus takes the Xorg process up to 95-98% on this Core Duo 2.4Ghz machine. Bringing another window into focus sends Xorg down to 1-2% again.

Worth noting is that I don't run a Desktop Environment, preferring a light window manager.

I greatly looking forward to being able to produce videos with Kdenlive in future.

No, I cannot reproduce it anymore with Kdenlive on Ubuntu 10.04.
