Intel 2.21.8 Driver Takes Care Of COW Regressions
Written by Michael Larabel in Intel on 27 May 2013 at 01:01 PM EDT. 8 Comments
Just one week after the Intel X.Org driver was updated with support for all known Haswell variants and introducing some new copy-on-write support for cloning pixmaps, a new release has been warranted.

Today's xf86-video-intel 2.21.8 release is mainly to take care of some fallout from last week's 2.21.7 release with the copy-on-write support. It turns out that there were a cow COW-related regressions that hit Wine applications and were causing a memory leak when using the Mozilla Firefox web-browser.

While just one week passed since the 2.21.7 release, Intel's Chris Wilson made 17 changes to the Intel DDX driver. The full list of fixes/changes for this updated xf86-video-intel driver can be found in the mailing list release announcement.
