Whenever i move the mouse pointer after it has been at the same place for some seconds, i see dashes flicker at the bottom of the screen below the taskbar.

This also happens after certain intervals of time if the mouse pointer is not moved at all.

I have tried everything from changing resolutions of the screen to changing the preferred graphics card on my laptop. I also tried with different drivers but its of no use.

I tried this on Ubuntu 18.04 I also tried linux mint LTS 19.2. The issue persists there too.

My laptop is Dell inspiron 15 7537, core i7 4500u, 8gb ram, Nvidia 750M gfx

Thanks for your help in advance :)
