Strange display problem, unsure if hardware or software, on Lenovo Yoga 13

Hi!

We have one Lenovo Yoga 13 Notebook that shows some screen issues.

As you can see in the following images, there are orange "lines" appearing in the upper third of the screen sometimes:
img_8506
img_8504
img_8505

The strange things are:

- the lines are triggered by mouse pointer movement, not physical movement of the notebook or display hinge
- We can only trigger these lines in Microsoft Visual Studio, however, we can trigger them in Visual Studio 2013 as well as 2022

There are 5 days of warranty left on this device and I am afraid that Lenovo will laugh at me if I claim this as a warranty problem. It seems rather like a software- than like a hardware problem to me.

Has anybody else ever seen something like this before?

I've never come across this myself before.
It really looks as if this is a software error because it is so specific. However, it is also possible that the GPU is picking up something (frequency or whatever, or even just a cable error) with these two programmes, which then makes a hardware error visible on the display in combination with the GPU.
I would rather let Lenovo laugh and turn it into a warranty case.

Hi,

might be a driver problem, have you ever updated driver of GPU and mother board?

This problem was only brought to my attention today. I am currently updating drivers to see if that fixes the problem. But due to the short leftover warranty I wanted to ask immediately if anyone has seen this before...

Have seen a similar problem on a Lenovo, the problem was bad soldering of the GPU-Chipset so slight pressure on the keyboard or mouse pad leaded to theses horizontal lines because of motherboard bending. It was fixed by reballing the GPU chipset. Before sending to repair check the functionality under a live linux, if this problem does not appear here it's a software rather than a hardware problem..

Hello, I've seen such display errors with faulty GPU RAM.

When does this error appears?
BIOS? Linux Boot Stick? Windows safe mode?

Hey,

does the error occurs even if you boot an Linux live Stick?

The problem is that the error appears rarely and is difficult to trigger.

I have finished the driver updates and was not able to reproduce the error since.
Currently my colleague who works with the notebook is trying to trigger it a bit more extensively.

Haven't tried a Live Linux yet.

My first thought was also bad soldering or problem with the display cable, but the problem appears (appeared?) even if you were moving the mouse cursor with a wireless mouse with absolutely no physical movement or pressure to the notebook.

I am hoping that the driver update fixed it.

Update the BIOS and Chipset too.
There is not much more you can do.

To keep the System up to date have a look at "Lenovo Vantage", available at Microsoft Store
When installed you can run a System update check. If there are any updates available, Vantage would install them.

I did update all drivers and BIOS using the vantage tool, behavior didn't change.

While the problem originally seemed to only appear in Visual Studio, during the investigation it turned out that it also appears in other applications like the file explorer.

Laptop is sent in for warranty now.
