Ubuntu – Distortion during window-resizing, typing in the address bar of firefox and in other places


I'm facing a screen distortion problem, when I'm trying to resize a window. It can be a window of any application, like file manager, VLC, Firefox, anything.

The distortions happen in flashes, like blinking- distortion and then normal again, then again…

The distortion isn't permanent, the window becomes completely normal when I'm done…

It doesn't happen all the time, but it happens and that's what's been bothering me…

Below is a screen-shot of what happens:

Window distortion

Also, I've noticed that when I'm typing something in the address bar of Firefox to Google something, the suggestions/suggestion bars also blinks with similar distortions…

I'm also noticing these type of problems when I'm going fullscreen on VLC, and then back in normal window mode…

It seems whenever there's movement, the problem occurs…

I'm editing this post to add more issues, and I still haven't gotten any solution here yet…

I know it might be nothing, but it's still something; I mean this shouldn't happen right?!

I'm sorry, in advance, if my question is too trivial or minor to even consider as a user…

This issue may not be related to the kernel, because it might be solved using some other methods, but changing/downgrading my kernel from 4.10.0-28 to 4.4.0-28 seems to have solved the distortion issues...

I have also used kernel 4.4.0-89 and that also seems to work fine. I tested using these kernels only because I used to use them on Linux Mint, so I trusted them to see if they can get me out of this problem...

From a similar point of view, I upgraded my kernel from the default 4.10.0-28 to 4.10.0-31(the update was available in the Software Updater utility) to see if that solves it, but it didn't...

So far, I haven't faced any distortion issues on these 4.4.0-x kernel series, neither in Firefox, nor in resizing application windows and other cases...
