Hello,
since my problem is very similiar, I thought I attach it to this topic:
I have horizontal lines occasionally popping up as soon as something is moving on screen.
It's not really a flickering, they just appear and disappear.
Since I am not able to make an actual screenshot of it, because it only appears for one or two seconds,
I manipulated a screenshot to show how it looks like:
This can happen inside a video window, but it doesn't happen when the video is playing, but when you pause it and the overlay of the player pops up,
then a black or sometimes white line pops up, as long as the overlay is shown.
This happens in many different applications, Photoshop, Firefox, VLC Player, ACDSee or the Windows Explorer.
Sometimes its only a picture on a website or a drop-down menu in some program.
Only Games seem to be immune to this, I tried a few which didn't show this error.
The thing is, I had this on 2 quite different notebooks.
On an MSI-CR61 with a Pentium 3550M + HD Graphics, and now on a Lenovo Thinkpad Edge E540 with a Core i5 + HD Graphics 4600.
Both running on a fully patched Windows 7 x64 SP1 + latest drivers.
I tried out a Linux Boot CD on both systems, on both the error is not present under that system.
Only under Windows 7 x64 SP1.
I haven't tried an external monitor yet, but I could do that.
On the MSI-Notebook I tried v.15.36.7.64.3960 of the Intel driver and the 2 versions before that.
On the Lenovo I only tried v.15.36.7.64.3960.
Any ideas?
Greetings,
Kaihro
