This is a pyopengl / pyopengl accelerate installation issue, not an xpra issue. Please report it there, not here.

PS: please use attachments rather than overly long tickets in the future.

As per FAQ, this particular error was caused by mixing distribution installed opengl with a pip install of the accelerate module. The versions must match!
