Bug#900821: workaround confirmed
It appears some StackOverflow users also see this: https://superuser.com/questions/1483696/cifs-mounted-on-linux-from-windows-shows-corrupt-distorted-images I could not find anything on bugzilla.kernel.org though :-( Maybe someone who can reproduce the problem should talk to upstream about it...

Damn, I was wrong! It is still reproducible - sorry for the confusion.

Hi all, we were experiencing this bug in a debian 10.4 docker container (FROM php:apache) it only happens with plain http not with https. I can confirm that workaround from Stefan Fritsch by turning EnableMMAP off is working for us! Cheers, Florian
