Hello, may I ask what resources Krita is drawing on? Am concerned about the 2 major vulnerabilities in the news and possibly having to upgrade kernel to 4.13, which will have the patch for the vulnerabilities included. There are many reports saying the patch slows down the system, and I'm worried Krita would be adversely affected. The 3.3.2 appimage runs very well on my present system, and I'm working at 16-bit, 300dpi, layers, etc. Thanks.

We simply don't know... I am not aware of a tool that will give us the % of time spent in syscalls vs userspace.

Thanks for response. I'll test 4.13 generally today, and, if there are no issues with that, I can report back later about how the patched 4.13 runs as regards Krita.

Just to feedback that both patches (4.4.9-108, and the active 4.13.0-25) work perfectly ... Krita is working just as well as before, as is everything else. Waterfox patch also, mitigated by some about:config tweaks, also no issues at all.

EDIT
New kernels 4.4.0-109 and 4.13.0-26, plus the new 20180108.1 microcode, all work fine too.
