Description

I am not aware of their severity. A quick search reveals that they haven't been reported.

I tried to truncate the 1+ occurences to minimize the text spam

Please try r23971 or later.
There is a beta 4.0 build for mswindows: https://xpra.org/beta/windows

As per the command line output:

Warning: vendor 'Intel' is greylisted,
 you may want to turn off OpenGL if you encounter bugs

This looks like an Intel driver bug.

If the bug still occurs, please attach the output of OpenGL_check.exe -v.

The error from _process_cursor may or may not have been the same, so it may still be present.

Status:	new → assigned

This bug is actually a duplicate of an old bug: #1358.
Now that we have a subprocess to probe the opengl driver (#1994, #2204), we enable opengl rendering on more chipsets, including Intel.
The problem here is that this error is fairly minor and didn't cause a crash, so we ignored it.
We should catch all errors, including minor ones, so we can deal with them and only enable opengl on a clean setup.

I found some other references to it, so we may also be able to fix the underlying cause too:

OpenGL invalid framebuffer operation after glClear(GL_COLOR_BUFFER_BIT); : Check the status of the framebuffer using glCheckFramebufferStatus and make sure it returns GL_FRAMEBUFFER_COMPLETE
GL error on mac after using pyinstaller
unknown error code (related to FBO’s?) : The error INVALID_FRAMEBUFFER_OPERATION_EXT is generated if the value of FRAMEBUFFER_STATUS_EXT is not FRAMEBUFFER_COMPLETE_EXT when any attempts to render to or read from the framebuffer are made.
