Hello @grepwood, as a side note, https://bugs.gentoo.org/616402#c15 may interest you.
Is there a second video card involved in the setup? What is the hypervisor using to render to the display?
Thank you @kisak-valve, I'll give this a shot. Meanwhile, I've also tested this with stock nouveau from Ubuntu 18.04 LTS. The free drivers also exhibit this strange behavior.
I followed the advice in https://bugs.gentoo.org/616402#c15 and I'm running into the same problems as https://bugs.gentoo.org/616402#c17.
I have gone a step ahead and altered the CFLAGS for these packages. They were:
CFLAGS="-O2 -pipe -ggdb -march=znver1"
And now they are
CFLAGS="-O1 -pipe -ggdb -mstackrealign -march=486"
This will not work for these packages, as setting -march=486 for amd64 code will trigger the compiler to not compile as 486 doesn't support any amd64-specific machine code. So, to work around this, I have gone with
CFLAGS="-O1 -pipe -ggdb -mstackrealign -mno-sse2"
This will still prevent sys-libs/glibc from being built:

Goodness, what a mess. I think I'll need to research how RedHat and Ubuntu make their GNU libc to rectify this sideshow for good.
Hello @grepwood, are you still experiencing this issue on an up to date system?
@kisak-valve I have not been able to even start Civ5 and CivBE since then, courtesy of https://bugs.gentoo.org/616402 and Aspyr defending their idleness tooth and nail.
Thanks for the feedback @grepwood, I'm going to close this issue for now because there isn't a good way to reproduce the issue, but if you get the testing blocker worked out in the future, let me know and I can re-open the issue.
Nothing extracted yet.
Your system information
Please describe your issue in as much detail as possible:
I have a virtual machine with Ubuntu 18.04 LTS for amd64 with a dedicated GeForce 710GT, running the binary nVidia driver, that runs Civilization 5 on Steam. My hypervisor is Gentoo Linux, which can't unfortunately run this game due to bugs. After launching the game, I try to stream it from my hypervisor, but I get really messy colors.
For the record, I have used the suggestion from #5434, but to no avail.
