Re:Lenovo Yoga C940 screen glitches, flickering, flashing

2021-01-14, 15:49 PM

I've now disabled Windows update, it's more trouble than it's worth. As a DJ machine I need to keep it stable.

 

I never ever updated my Yoga 2 Pro (Windows 8.1) it just ran on the factory build and I never ever had any issues with it.

 

The C940 may be better hardware ways but it just doesn't give me the same "reliable" feeling that the Yoga 2 Pro did.

Well it worth disabling it yes.

Maybe this will be my last windows device after those experiences i dont know.

Now it seems the problem is solved yes. But the headache it gave to us was really worth to change the OS.

Well I have also had a bootcamped Macbook Pro 16" For over a year now running Windows 10 Pro and it's been absolutely perfect. Used every day and not a single glitch anywhere.

 

I'd suggest the issue is more Lenovo than anything else. The fact they couldn't even be bothered to respond to a 22 page thread tells it's own story.

As others have done I manually installed 9126 from intel's website.  This resolved the problem but introduced noticeable lag and delay in loading and scrolling through pages in chrome.  I tried to live with the lag but it was too bad and rolled back the drivers.  Anyone else notice a performance dip with the 9126 driver version?

It is possible that maybe they are disabling the hardware accerelation feature in this model cpus with this driver

And maybe this is why our problem is getting solved but ur games are getting slower.

 

This is just a guess tho.

Well, Windows Update has just foisted this lovely up-to-date (not) version on me:

 

 

I might leave it though, as this morning's updates came with some Lenovo cruft as well as the cumulative update for Windows 20H2. Perhaps I'm expecting too much of Lenovo/Intel/Microsoft but maybe this is a known good combination being pushed out? We can but hope. Otherwise, I'll put 9216 back on.

 

Edit: well that lasted literally half an hour before manic flashing and task bar replication. So stuff that, 9216 is back on mine now.

Yes,

The most stable one without any issue is 9126. I can live with this driver. This is not a gaming machine or something so for me this driver can be with me forever. I wont update any of next ones maybe. Or maybe just to try the new ones if it will be any issue with them or not.

Hardware acceleration is enabled in the latest drivers

 

edge://gpu/

 

chrome://gpu/

 

just copy and paste into browser.

 

Hardware acceleration "could" slow down browser experience, but this might be solved with new drivers (or not).

 

Regarding ms updating or more like downgrading the driver. Use WUshowhide to hide the updates from installing. if the gfx installs just upgrade again to the new one.

 

Still working great here
