Intel HD 530 low performance in chrome/chromium with kernel 4.14

I have low fps during scrolling pages in chrome/chromium only with kernel 4.14.x. Now I have to use lts-kernel to avoid this problem.
In benchmark (unigine) kernel 4.14 have the same result as lts or 4.13 kernel and now I'm afraid that all the kernels since 4.14 will have this error for me.

kernel log:

My laptop Dell E5570 with i5-6440HQ and Intel HD Graphics 530.

Kernel 4.15rc5 still have this bug.

xorg.log

And with 4.14/4.15 kernels I have a strange dmesg after plug\unplug AC on my laptop:

[   64.104856] acpi INT3400:00: Unsupported event [0x86]
[   69.347228] acpi INT3400:00: Unsupported event [0x86]

Re: Intel HD 530 low performance in chrome/chromium with kernel 4.14

Bisect between 4.13 and 4.14 and report the issue upstream?

It's kinda weird that only scrolling in chromium would be affected.

Desktop environment? (unigine is maybe unredirected by the compositor)
The dmesg isn't long enough (apparently taken directly after the boot), but did you try to disable framebuffer compression?
Does this meet your problem: https://wiki.archlinux.org/index.php/In … 28VSYNC.29 ?

Desktop environment

gnome 3.26

Disabling frame buffer compression, vsync and falling back to "DRI2" has no effect.

I don't have any logs confirming this issue, and I can't understand where the problem. I have only this:

Does it also happen with gnome on wayland?

Unfortunately, yes.

4.14 kernel has the issue you downgrade to 4.13 or 4.9 and the issue is no longer present without changing anything else then the issue would seem to be caused by some kernel change between 4.13 and 4.14.
Ideally with bisection you would get commit A no issue commit B issue and you can report to upstream the issue starts with commit B.
Other scenarios would be:
1) you build 4.14 locally and can not reproduce the issue then the issue is related to the build system.
2) You have commit A no issue commits X Y Z which will not boot or have other issues that make testing those commits impossible then commit B with the issue so you can only report X Y Z or B is causing the issue.
You could report the issue how-report-bugs upstream without the bisection but it may be harder to diagnose the cause.
As 4.14 is due to be the next linux-lts you would have to start building your own kernels based on 4.9 lts when arch switches to 4.14 lts unless the issue is resolved.
