Hi

I'm on Debian Stretch but I'm not experiencing the issues you're discussing 
here. However I remember to have had similar issues with Plasma 5 and Intel 
drivers. As a workaround I used this /etc/X11/xorg.conf.d/20-intel.conf:

Given also the previous messages about this topic, enabling DRI3 indeed seems 
to solve the problem. Anyhow, I discovered that the problem was with the i8xx 
i9xx display driver, provided by the automatically installed 
xserver-xorg-video-intel package, which could be not required by new hardware 
as reported in the description:

I tried to uninstall this package as suggested and the problem was solved:
