--- Comment #30 from Spricer <mileek at gmail.com> ---
I can confirm this bug as well in Mageia 5 latest kernel.
C/P from my post there:

After booting into 4.4.13-desktop-1.mga5 screen starts flickering/going blank
for second when switching mouse from one monitor to second monitor. Sometimes
screen stays black after leaving it with mouse and moving mouse back restores
screen. This is NOT happening with  4.1.15-2.mga5 kernel
