I get his odd artifact when ever the screen comes on from being off. It is always in the same spot. I can move the cursor over it and the cursor will look normal but the artifact is still there after I move the cursor away. If I drag something like an icon close to it it'll disappear and look normal until the screen turns off and on again. This also only happens when the brightness of the screen is set to the highest. The laptop has Nvidia 540M GPU and I have the latest drivers.
Does anyone have any ideas what can be causing this?
