Please attach some screenshot. My feeling is that this is completely normal as not all cursor attributes can be transmitted over the RDP channel.

I have attached two screenshots made with my camera. It's just one example. I have the same problem with all other (pointer alone, hand with one finger). Sorry, i don't know if i use the right english words for theses mouse pointers names...

When i use rdesktop i have no problem.

Thanks in advance, Olivier.

After more tests i have more informations :

  • I don't have the problem with rdesktop 1.6.0 (Debian 6.0).
  • I have the problem with rdesktop 1.7.1 (Ubuntu 12.10).
  • I have the problem with rdesktop-vrdp 1.7.0 (Virtualbox 4.2.10)

  • Status changed from new to closed
  • Resolution set to invalid

Please disable mouse pointer shadow in the XP guest: uncheck Control Panel/Mouse/Pointers/Enable pointer shadow. Then the pointers will be OK with rdesktop 1.7.1/rdesktop-vrdp. In principle this is not a VBox problem. We will add a workaround in rdekstop-vrdp.

Pointers with shadow use 32 bits per pixel (with alpha channel).

rdesktop 1.7.1 tells the RDP server that 32 bits per pixel pointers are supported. However it can not display such pointer correctly.

rdekstop 1.6.0 does not claim the capability and the VRDP server converts 32bpp pointers to a simpler format.

ms rdp client of course supports 32bpp pointers.
