I am also experiencing the exact same issue on KDE Neon 5.10.4 and
nvidia-384.59, and switching to Xrender also fixes it for me.
Note that for me turning off compositing while using OpenGL 3.1 had a
salutory effect but did not completely resolve the problem. For

I updated from Kubuntu 16.04 to 17.04 a few days ago to fix some other
issues with frequent crashes and on Kubuntu 17.04 am now also affected

I tried updating nvidia driers to 381 and 384 but I could detect no
difference between 375, 381 and 384 (from ppa:graphics-drivers/ppa). For

Like Loïc, I also use an external screen, with the laptop screen turned

I use dual screen quite often but not always. This behavior is the same

Bugs,
I can confirm this issue, I have the same problem since zesty update.
I cannot use apport-collect to complete information as I'm also affected
by https://bugs.launchpad.net/ubuntu/+source/apport/+bug/1627790
So here's too much information !
If you need more please just ask away.
