No, with other postprocessing projects, such as the shader postprocessing workshops, it does not happen here. But it's hard to tell because the effect is rare. It looks as if the data buffer on the 3D card jumps out of sync for one frame dependent on the content of the image. I'll check the problem in more detail in the next days.

If you have a _simple_ project where this problem happens too, please send it to the support. Maybe the reason is something in the shader code.
