Aye. Thank you!

I have a XPS 9343, and am running into the same issue. Adding sna fixes the slow down in Firefox, but i'm getting weird artifact on some sites including linuxQuestions. In any of the text entry fields as I'm typing the text will get garbled up.

rebuilding with

--with-default-accel=sna
--enable-glamour

didn't seem to have any difference then adding the 20-intel.conf file.

I didn't have this issue on current until awhile ago. Sadly I can't remember what update.

I think glamor acceleration might be removed now so it might not matter. I would first grab the source and run ./configure --help to check any options.

xf86-video-intel-git_20160408_de44aaa fixed the graphical glitches for me.

Yea those changes to the configure script won't fix anything other than defaulting to 'sna' so you don't need to add anything to /etc/x11/xorg.conf.d/

I added a dirty hack to pat's get-xf86-video-intel.sh script to download and package a specific commit. https://pastebin.mozilla.org/8867114

In my fiddling this morning
afddc9f - This is the version in --current and gives me terrible artifacts
e783ff - version ppencho built. For me it's mostly ok with very small glitches every now and then in libreoffice
de44aaa - current HEAD, mostly ok with small glitches, same as e783ff
59d371 - Works the best for me, haven't noticed anything out of the ordinary yet.

There have been ~11 commits in the last two days. I don't know how you're supposed to grab a stable version..

Thanks, that was helpful.

I just installed xf86-video-intel-2.21.15-x86_64-1.txz from Slackware 14.1 on 14.2 and all the issues I was having went away. Someone correct me if that is an horrible idea.

I tried building 59d371 and its a bit better then de44aaa, but still getting the glitches. I have no reason to use sna over uxa, but the build on 14.2 is unusable for me. I wonder what changed in Slackware's build to make uxa problematic, or this is a regression in the driver. I couldn't find the config in 14.1 but didn't dig much either.

Hi!
Today i build the latest driver from git and all issues disappeared!
I use sna and firefox - libreoffice and my xfce desktop running all smooth...

Maybe to check again because sna have 2 new commits now in git?

Hi,

@Panagiotis Nik I can confirm that b6917ec solves many problems, but have a look here.

Problems with b6917ec when I drag windows in KDE (attached image).

With 59d371 (as reported by D1ver) I can't detect any issues (installed yesterday).

Hi,

When starting up Scilab, I observe the following error:
The applications starts, but there are fonts corruptions.
Maybe it's related to Java font handling?

I'm on SNA of course.

The stable version is 2.99.17, released in December of 2014. Tarball here:

http://xorg.freedesktop.org/archive/individual/driver/

That's the version that's in the driver's official 2016Q1 stack release:

https://01.org/linuxgraphics/downloads

My understanding is that X.99.XX releases from X.Org are development releases and are no more guaranteed to be stable than a git pull from that day. But if I'm wrong (or if 2.99.17 just happens to work better), say something about it here and perhaps we'll consider using that one instead. Given the issues with this driver I'm tempted to drop back to the xf86-video-intel-git_20160229_d167280 version, since that one didn't seem to get any reports of artifacts or other problems.

Hi,

I think you're correct.

I'm not gonna bother to check myself, but does 2.99.17 have Skylake support at all?

Hi,

It is going to be a bit of hit and miss. I switched to d1672806a5222f00dcc2eb24ccddd03f727f71bc and still have font corruptions is Scilab. The question is, if it is related to the intel driver?
