[SOLVED]Chrome/Chromium lag

Usually I never ask for help on forums, always been able to find solutions to any problems by google, wiki, etc. But this one driving me mad. I'm enjoying using arch linux - best distribution I ever tried. Simple, minimalistic, everything works great except Chrome browser lag. It happens on scrolling some heavy sites like google+, but not always, it can be some simple forum page scroll when if face horrible lags. Particulary when scrolling backwards to top of the page.  But for other sites, like this forum for example, everything is butter-smooth. Firefox renders everything smoothly, but gives screen tearing. Tried some other browsers like qupzilla (same lag as chrome) and palemoon (tearing like in firefox). I tried many things: compton (which gave me tear-free in firefox, but same lags in chrome), fallback to modesetting driver (video is intel hd3000), other kernels (lts, ck, pf), mangage to enable hardware acceleration under chrome://gpu (all green lines), some kernel parameters in boot entry (enable_fbc, enable_rc6, semaphores). Nothing gave positive results. The system is T520 thinkpad with i7 and nvidia card, but it disabled in bios. I3 window manager without compositor. With the same setup no lags in chrome with ubuntu, which I don't want to use because of big list of other problems.  So I'm desperately asking fot help in hope that someone faced this problem and found a solution.

Sorry for bad text and mistakes - I'm not so good at english.

Re: [SOLVED]Chrome/Chromium lag

This seems to be a driver issue. Try to figure out what could be different from Ubuntu. Look at /var/log/Xorg.0.log and see if there are any error. Check the output of glxinfo (particularly glxinfo | grep -i render). Check glxgears and its output (you should have 60fps no more, no less: this sync with the refresh rate).

Since things work in Ubuntu, try to compare with Ubuntu and see if there are any difference.

Re: [SOLVED]Chrome/Chromium lag

Well, it seems that the issue was a combination of different factors, and for some of them I have to blame myself. It happens only on xf86-video-intel driver and not on modesetting. But because I already mess with some flags in chrome://flags, I saw lags anyway. Also, touchpad driver is different in ubuntu. I could have investigate further, but only have arch installation right now. Glxgears shows 59,6 fps, refresh rate of the screen is 59,99 (according xrandr), so I suppose it is normal? No errors in /var/log/Xorg.0.log except:

SynPS/2 Synaptics TouchPad: Failed to create a device for /dev/input/mouse1
PreInit returned 2 for "SynPS/2 Synaptics TouchPad"

But it works normally. Anyway, thanks for help.

Re: [SOLVED]Chrome/Chromium lag

Hello mooncactus, I also has the same problem with intel hd2000. Browsers work fine in ubuntu but have tearing/lag in arch. Can you explain how you solved your problem? Many thanks.

He mentioned that in the last post, in general using xf86-video-intel as opposed to the built-in modesetting driver might lead to such issues

Re: [SOLVED]Chrome/Chromium lag

Actually I found graphical perfomance on lts kernel much more reliable, fluid with no lags in browsers and other applications, just like in ubuntu, if not better. I have tried kernels 4.10, 4.11 and 4.12 as they were released, overall perfomance was slightly better (placebo?), but stuttering in chrome always come back. So I stop worrying and loved the lts kernel. And no actual difference with drivers: all good on both sides (xf86-video-intel and modesetting).
