Play-head Disappears When Moved.

[Brendan Foley]

Using: Ubuntu 10.10
Install: Synaptic, Ubuntu Repository list
Version of OpenShot: 1.2.2

The Play-Head (including red line) dissappears when it moves in any way, and does not reappear until restart, but will disappear again as soon as it moves. This includes when "play" is pressed and when jumping positions on the timeline. This started happening yesterday, and I'm not sure why. I've tried re-installing Openshot with the same result.

Upon further testing I found that this only happens when I load a particular project. I can add clips (including clips from said project) without issue, and I can play other projects without issue (to an extent). However, if I load the problem project the play head will disappear (it looks like it goes behind an invisible screen actually, as it incrimentally changes moving into a position before the first hash mark). Then, if I try to add a new project, the playhead will disappear there, and if I import and add a file, the file will not show up on the timeline (though if I hit play it will play). I can still jump around through the timeline in both cases by clicking on a position, but I will not see the play-head at any time. I've also tried loading different projects after the first project has a problem and they initially show the play head, but then do the same thing with the play head disappearing at the same point (unless I restart OpenShot and load the other project first).

This is a very strange error that I can't figure out, and when I run openshot from terminal I don't get anything unusual at all, no errors or fails, just standard 'clicked with' 'called with' etc. commands at the appropriate times.

I can't figure out any difference between the projects either.

While trying to get a screenshot to show, I also discovered that 1) if I change the zoom on the timeline the playhead will flash at the beginning of the timeline (but only flash), and 2) If i stop the play in the middle of where it begins to disappear the playhead will continue to move into disappearance.

I've attatched some screenshots to help.

UPDATE:

Ok, figured out another piece of the puzzle and a "fix".

This seems caused by opening an osp file that is saved at a 1 sec timeline zoom. Zooming out, even before play, will not prevent the bug. However, saving the project zoomed out from 1 sec., restarting openshot, and reopening the project will fix the bug. Likewise, I can cause other project files to cause the same bug by zooming into 1 sec and saving and trying to open them again from said save.

Why this effects other projects opened in the same session that were not saved at 1 sec. is beyond me, but thats how you fix the issue and cause it. At least on my machine.
