Mouse/trackpad issues on Ideapad

Good day everybody.

I am somewhat new to Linux, have been using Mint 19.1 Cinnamon for a few months now but wanted to look at something “lighter” and installed netrunner 18 idolon yesterday (dual-boot). I am quite happy with the look and feel and would like to make it my default os. BUT I have some very irritating problems with the trackpad and mouse.

My system is a Lenovo Ideapad 110-141BR with 4 Gb RAM and 1TB HDD and Elantech trackpad. The mouse pointer goes crazy whenever I move the mouse, pointers all over the place, in every app I use. Some are worse than others. The video in SMplayer is fine in full screen but a few pointers show up in windowed mode. Yarock and Audacity is just about unusable, I never know which pointer is actually mine. In Konsole and sometimes in other apps little blocks with what seems to be part of other windows appear at random. Disabling the trackpad (Fn+F6) has no effect on this problem.

Please help! I would LOVE to keep on using this distro but it’s driving me crazy!

The issue seems to be a graphics driver issue. Not redrawing the mouse cursor correctly. Have you tried changing the OpenGL Version in systemsettings -> compositor? Maybe it fixes this.
If not try disabling compositing alltogether by pressing ALT+Shift+F12 and see if it fixes the issue.
If it does disable the automatically compositor start in systemsettings -> compositor.

Which graphics card do you have?
Which driver are you using? (See kinfocenter or systemsettings -> about)

Hi leszek.

You were quite correct, it was the OpenGL driver. I changed it from 2.0 to 3.1 and the problem has disappeared. It did surface briefly when I opened Firefox to reply just now but went away immediately.

FYI my graphics card is Intel x5-E8000/J3xxx/N3xxx (integrated) according to inxi -F.

Tx ever so much!

EDIT:
The 3.1 driver still caused some screen tearing as mentioned earlier. The XRender driver has been working absolutely perfect for the last 3 days.
