I don't know to which regulations / guidelines you refer by 'valid',
(the RFCs?) but I *think* "(no subject)" is valid, as in, it's not empty.

And yes, forgetting these things happens, thanks for pointing that out.

To me, this absolutely renders calc *unusable* for large plotting and
graphing purposes. They take at least 3-5 times longer, I've as a
temporary solution done my graphing on a virtual windows in OOo.

That being said, please read on.

So, I was using Cairo (Hardwarebeschleunigung), but unchecking this
didn't change anything. Whereas unchecking the button below, "Use
Antialising", almost resolves the issue. Nice and smooth afterwards. But
since that obviously isn't the root cause of the problem, I've done what
you suggested and here are my results:

vanilla .deb from OOo, Version 3.1.1 for Linux x86_64: Same problem,
after enabling Antialising. But, and probably worth mentioning:
Antialising is disabled by default, as opposed to the debian standard.

Vanilla .deb from OOo, Version 320_m2_3.2_beta_LinuxX86_64: I couldn't
get the Beta to work. It complained about missing dependencies to core0X
files, which weren't included in the download, not even after
downloading a second time....
