Scientific Linux > Installation and setup support > SL 7.3 Screen Tearing Issue when moving window

Posted by: harishpathangay Mar 12 2017, 08:00 PM
I have installed SL 7.3 on VBOX 5.1.0
Up and running Cool. Also installed Guest Additions. Cool with that too.

But I find screen tearing or when I move window left to right, I observe screen tearing or breaking up. it is not very fluent.
How to fix it?

i am a newbie Linux person.
sometimes do I over exaggerate things. I do not know.
you tell me after viewing video. what is wrong during window movement? it stutters when moving.
is it screen tearing or compositor issue or software issue? I do not have any idea other than observed result.

small size only - 3MB

will I get any inputs this time ?

I am sorry that nobody has responded to your request for help. sad.gif I suspect it is because no one is sure what is causing the problem.

One difficulty is that you are not running Scientific Linux natively on the hardware but are running it as a VM (virtual machine) under VirtualBox. I think it might be worthwhile asking for an opinion in the

Asking in the VBox forum is a good idea as I do not think this is SL-specific.

I watched the video. But I failed to see the problem there. Are you referring to "not so smooth" movements? It could be due to a hardware issue. Graphics rendering is slower than required or something?

yes I mean that stuttered movement when moving windows.
that is okay it is not a show stopper. as long as os works with out crashing I am fine.
I thought it might be some simple setting I am missing. but it sounds deeper than that.

I raised on VBOX forum and Cent OS as well. All are suggesting to run it in real hard ware. I can't run it in real hard ware because I need 2 VMs for my activity.

but that is not a show stopper. I am fine as long it is stable.
Please consider case closed.
