My recent project edited in 18.04.1 AppImage looks fine in preview, but
fails to either render or timeline preview render: aborting with CRC
errors in image files. Checked the image files, all fine, Kdenlive still
doesn't render. Rewrote these image files. Nope, still CRC nonsense.
Sometimes, playing the timeline even crashes Kdenlive.
The same project renders fine in 17.12.0d. Go figure. 18.04.1 is broken.
Period.
Best regards,
Harald
