GLError (invalid operation) in phy when running via RDP on Windows Server 2019

[MtKana]

Description

I am encountering a GLError (invalid operation) when running phy (installed via Conda) on Windows Server 2019 through RDP. The error occurs during OpenGL operations such as glClearColor, and I suspect it may be related to the remote desktop environment.

The error message I receive is:

An error has been encountered at line 1 of <internal MIME data>: Premature end of document.

Steps to Reproduce
1. Connect to Windows Server 2019 using Remote Desktop (RDP).
2. Install phy via Conda.
3. Launch phy.
4. The error occurs during execution.

What I’ve tried

Since my issue closely resembles #1018 #737 #945, I have attempted the suggested solutions there, including:
• Installing GLView (tested both version 4.x and 7.x) to verify OpenGL support.
• Modifying the RDP graphics configuration as per the recommended settings.

Unfortunately, the issue persists.

Debug log output

Running phy in –debug mode provides the following log:

04:25:53.852 [D] base:675             Exception in initializeGL: GLError(
        err = 1282,
        description = b'invalid operation',
        baseOperation = glClearColor,
        cArguments = (0, 0, 0, 0)
)

)

)

Questions
1. Is there any additional software or dependencies I need to install to resolve this issue?
2. Could this be related to OpenGL rendering over RDP?
• If so, is there a way to force phy to use a software OpenGL implementation (like Mesa)?
3. Are there specific environment variables I should set for OpenGL compatibility in this setup?

Any insights or suggestions would be greatly appreciated!
