dmesg from 4.8-rc1 with drm.debug=0xe
On Kernel 4.8-rc1 the mouse cursor flickers horribly when moved around and some
parts of the display (around the cursor) fail to update properly and flicker
randomly. Sometimes I have multiple mouse cursors on my display and sometimes
covered windows come through in areas around the cursor.
This does not happen on earlier kernels (4.6 and 4.7 work fine, for example),
so it must me a regression.
Hardware: Lenovo Thinkpad L460 in Ultra Dock with DVI+HDMI monitor
CPU: Core i5-6200U
Software: Arch Linux with KDE Plasma Desktop
Kernel: 4.8-rc1
Both dmesg and Xorg.log look normal.
