Comment 317 for bug 353126

I can confirm that I'm also having this issue on 10.10 x32 with nVidia drivers.

Was having this issue with 10.04 as well.

yes with Visual effects disabled you can get Client side info but with visual effects enabled it does not automatically disable when someone connects.

If you setup a vncserver :1 and higher the issue does not present itself...it only affects the main Desktop vncserver :0

in earlier versions there was a built in visual effects auto disable when VNC connected to the main desktop...but not since 9.14.
