Default OpenGL issues in Windows 2004/May 2020 Update

Since updating some machines to Windows 2004 (the "May 2020 Update") they are no longer able to run programs that rely on OpenGL (Google Earth Pro, SketchUp, ArcGis, others) with their discrete Nvidia graphics cards when connected to monitors through a D6000 docking station.

This seems to be a similar scenario to the issues that were initially present on the Windows 1903 update, as described in a few threads linked below:
https://www.displaylink.org/forum/sh...ht=1903+opengl
https://www.displaylink.org/forum/sh...highlight=1903
https://www.displaylink.org/forum/sh...highlight=1903

To summarize, these OpenGL applications will run perfectly fine if the laptop is not connected to the dock. When the dock is connected, they will run only if manually set to run with the integrated graphics (by selecting "Power Saving mode" from the Windows display options) or if either the Intel OR Nvidia driver is manually disabled.

Is this something that can be addressed on your end or something that will need to come from Microsoft? If the latter, are you aware of any work the issue or timeline?

Please let me know if there is any more information I can give you in terms of testing, logs, etc. Thanks you for your help,

Doug

Hello Doug,

The current issue looks like a graphics driver regression rather than an OS one.
If this is the same issue, downgrading to an Intel GPU driver version below 2x.20.100.7923 should help.

A bug has been created a couple of weeks ago with reproduction steps and observed regression point. It is going through the process.

Kind regards,
Alban
