Hi Jeff. Does this still re-produce on Windows?

Comment 6

[Jeff Muizelaar [:jrmuizel]]

We don't have the machine setup anymore so I may not get to this for a while.

Florin — I realise that you may not be the right person (apologies in advance if not), but I wondered if Softvision has the setup required and if someone in the team can have a look at testing and re-producing this specific issue. Any help - much appreciated.

I am in fact the right person for this :). 

We have the following NVidia GPUs on machines with Windows:
- NVIDIA GeForce 920M - seems to have Fermi architecture - https://www.techpowerup.com/gpudb/2675/geforce-920m
- NVidia GeForce GT 610 - seems to have Fermi architecture - https://www.techpowerup.com/gpudb/821/geforce-gt-610
- NVIDIA GeForce 620 - seems to have Fermi architecture - https://www.techpowerup.com/gpudb/820/geforce-gt-620
- NVIDIA GeForce 210 - seems to have Tesla architecture - https://www.techpowerup.com/gpudb/2020/geforce-210

Jeff, would you recommend any of the first three GPUs (all three seem to have Fermi architecture, if techpowerup is correct)? 
Also could you tell us what the Windows version was?

:jrmuizel - any feedback for :FlorinMezei based on Comment 8?

Hi Florin - Apologies for the late reply. Would it be possible to test on all 4 configurations?

Forwarding this to Andrei and Cornel to see if we can find some time for trying to reproduce this.

[Alexandru Simonca [:asimonca], Release Desktop QA]

Hello,
I have tried reproducing this issue using the following GPUs:
- NVIDIA GeForce 920M 
- NVIDIA GeForce 620
I wasn't able to reproduce the issue using Nightly 43.0a1 (id: 20150915030232) nor with the latest Nightly build. I have read the redddit post and tried everything mentioned there but still no luck. Jeff, did you get that machine setup again? Could you try reproducing one more time? 

I haven't tested the NVidia GeForce GT 610 GPU yet. It's on Florin's computer and he's out on PTO. I'll get back to it as soon as possible.

There's not a whole lot more we can do here.
