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.
I cannot run it:

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:
ImportError: DLL load failed: The specified module could not be found.
Was caused by r23803 and is fixed in r24004. Thank you for your patience!
Works on r24004 +
See also #2459, r24234 improves on this fix.
