intel graphics driver update causes artifacting skylake

I have been using the same hardware, and the same window manager (ctwm), for several years now - and have never had these problems ever.A new version of Skylake integrated graphics driver was included in the latest OS X El Capitan 10.11.4 update. What I really don't understand, though, is how did I only start seeing this issue now, when upgrading to Fedora 35. In any case, I think it won't affect most Fedora users (who use Wayland by default) but those who need it, will have a really hard time figuring out how to fix it (I was really lucky to find the aforementioned page - at first, I didn't even know how to call the ugly artifacts I was seeing). I think that maybe this option should be made the default, because whatever the negative side-effects of this option are, without it many applications look absolutely terrible. I couldn't find any negative side-effects, although the output of isn't great. With that, after restarting X, the tearing problems are completely gone. That page mentions a fix, which I tried, and worked perfectly! The fix is to create a file /etc/X11//nf with the content: It turns out that this is a known bug in the Intel driver, described in. I had the problems when I was using the ctwm window manager, but couldn't reproduce it with the default Gnome window manager.Īccording to my $HOME//.local/share/xorg/Xorg.0.log, my X driver is intel_drv.so, compiled for 1.20.11, module version = 2.99.917 and the actual chipset is 'Integrated Graphics Chipset: Intel(R) HD Graphics 4600' It seems that certain window managers somehow makes the system immune to this problem. In X11 the problem appears to happen - and is very visible - in specific applications such as telegram-desktop and wine, but I couldn't reproduce it in other applications.ģ.

The problem is just with X11 - with Wayland it doesn't happen.Ģ. I did a few experiments and noticed that:ġ.

After upgrading from Fedora 34 to Fedora 35, without changing anything in the hardware setup, I started seeing weird 'screen tearing' artifacts - e.g., when I move the mouse over a menu and the shaded item changes, the shade doesn't just move at once but for a visible fraction of a second I see some scan lines with the old color and scan lines with the new colors.
