Description farid 2016-08-22 18:52:26 UTC 
Two people in the studio are starting to work with Kdenlive and they use LinuxMint (I am not familiar with this system). Eveytime they add an effect to a track the project monitor turns black.

See video for more details.

Any hint on how to fix this?



Reproducible: Always

Steps to Reproduce:
1. Add a track to the timeline and press play. It plays normally in the project monitor.
2. Add an effect (brightness) to the track and the project monitor screen turns black.
3.

Actual Results:  
The screen turns black in the project monitor.

Expected Results:  
The effect should appear in the project monitor.

This is kind of back...

1- Add clip to timeline
2- Apply to it "Color Selection" effect
3- The project monitor turns black instead 

Clicking on the color picker icon brings the image back of the clip in the project monitor. Don't  know if this is like this by design but it might seem like a bug to many users.

Change defaults for Color selection effect so that we don't get a black screen at startup
