Description Unknown 2016-10-26 17:28:03 UTC

User-Agent:       Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:49.0) Gecko/20100101 Firefox/49.0
Build Identifier: 16.11.70

See video in URL field for example.

I created a title clip and put into the timeline, then added a wipe transition to the beginning of it. Problem is, the title is distorted during the duration of the transition, then appears normal when the duration is complete (it looks like the text is outlined instead of filled in).

Reproducible: Always

Steps to Reproduce:
1. Create Title clip (with gradient color), then add to Timeline above video clip.
2. Add a Wipe transition to the beginning of the Title clip.
3. Playback section in timeline.
Actual Results:  
The text is distorted through the duration of the transition, looks like it's outlined instead of filled in, and edges are extremely pixelated.

Expected Results:  
Font should look like it does in Title Clip in Project Bin from beginning of transition to end.

I'm labeling this bug as "major" because not being able to apply transitions to titles and have them appear alright is a major feature that's broken.

Bug discovered while using Kdenlive 16.11.70 git master build via ppa:kdenlive/kdenlive-master.

UPDATE 1: I should also add that the video clip below the Title clip in the video has two effects (from top to bottom): a Position and Zoom effect, and a Rotate (keyframeable) effect. Attaching screenshot of Properties widget showing effects for the video clip below the Title Clip.

This issue doesn't seem to be present in the current git-master build for Ubuntu. Marking this bug as resolved/fixed.
