cursor pseudo-encoding

[James Weatherall]

Hi Peter,

That sounds like a bug in VMWare's implementation of the RFB protocol.
Caret cursors are usually rendered to the screen via XOR, whereas the cursor
pseudo-encoding supports pixel & mask cursors, so it's quite possible that
their conversion between the two is missing or broken.

Regards,
