This is probably a problem in MLT's affine filter. Which MLT version are you using ? From a terminal, type: melt -version

Can you tell me what is the size (widthxheight) of the image "banner.png" used in your project, or even attach it here? Thanks

I was trying this tutorial https://opensource.com/life/15/8/adding-lower-thirds-kdenlive and appears same problem when I crop and resize the Color Clip. (I'm new in Linux and english language, be patient please...)
Thanks for the details and the video. I can now confirm the bug. It is a problem with the "affine" filter / transition that is part of MLT. There are several issues with this effect / transition that are not easy to fix. Because of this, I wrote a new effect / transition for MLT a few months ago that has the same features fixes these problems. You can find the effect under the name "Transform" and the transition under "Composite and Transform". Do you have these available ? I should deprecate the use of Affine transition for Kdenlive 16.12 (added on 16.12 roadmap: https://phabricator.kde.org/T3788 )
I have both effect / transition. Thanks for your work and time.
I've tried with recent frei0r/MLT fixes and a problematic project of mine where I saw this kind of corruption as reported here; it's gone now. So I'm now closing this as resolved fixed. As for the Affine transition: a quick poll in our G+ community (https://plus.google.com/103555172011502893674/posts/ijcVd2FsbKa) showed that 16% out of 31 Kdenlive users use Affine on a regular basis as their most-used transition. Deprecating Affine won't do much good, me thinks.
Hello, in addition to the problem that was fixed, some other effects have white lines/dots when used: rotate and shear, rotate (keyframable), distort. $ melt -version melt 6.4.1 Kdenlive version 16.08.3 KDE Frameworks 5.27.0 Qt 5.7.1 (built against 5.6.1) The xcb windowing system Best Regards, Andrej Mernik
