"This issue appeared because of a Linux kernel change in version 4. The
new Intel graphics driver uses SNA (Sandybridge New Acceleration)
architecture for graphics acceleration by default. When coupled with the
kernel change, the driver causes this issue. Thanks to Fedora's active
community, bugs were filed in Bugzilla (Bug 1226531 and Bug 1226743) and
fixes are on their way. An update to *Intel driver is already in stable
updates*, and a kernel update (to v4.0.5) is in updates-testing repository."
"Instructions for installing the fix and for working around the driver
issue are provided in the article":
