hi,

To anyone who's testing, have you tried the effect "Position and Size(GLSL)"

If the Timeline cursor is over the clip you're adding it to, kdenlive takes a dive.
Move the cursor out of the way and then add the effect, it appears. I spy no keyframe so I add one at the start. Move cursor back and no crash. It still doesn't seem to be doing much but before I have a chance to investigate further it crashes.

Anyone?

I see so many crashes that I cannot use current Kdenlive builds in even the tiniest meaningful way. If you call this diving, then I would add that Kdenlive has slight problems controlling its buoyancy. As soon as it sees any water, it's immediately deep down.
