Title:
Kubuntu 18.10 Xorg severe memory leak
Status in xorg-server package in Ubuntu:
Confirmed
Status in xserver-xorg-video-vmware package in Ubuntu:
Confirmed
Bug description:
Suddenly sometimes during the past two weeks my kubuntu installation
has started to freeze up. I can't remember what apt upgrade that
caused it, and I have done several the last few days hoping for it to
be resolved.
I didn't know what was causing it as I hadn't made any other changes
expect for the odd apt upgrade. Before that I had just finished a
several weeks long session of intense work around the clock without
having to reboot even once. Suddenly it is now freezing up within
hours. Even without doing anything, just leaving the computer alone.
However, yesterday I accidentally discovered that my RAM was filled
up. More than filled up, even all swap was full. And before I could
close anything down it froze up again.
So TLDR; I have today logged the memory consumption while I was
handling some bills and linked is a log of constantly increasing Xorg
memory usage. So it goes until it chokes the machine and only a hard
reboot is possible.
My installed RAM is 10GB. Swap is 6GB. Please refer to the linked file to see
how the Xorg usage creeps up.

I should add that this bug seems specific to Kubuntu, and (I guess)
associated with running under Virtualbox. I have another Ubuntu 18.04
(i.e. not _K_ubuntu) running on bare metal and it is not having any
problems.
Please advise what additional information I should post to have this
resolved.
