Please note that this message will contain a full copy of the comment thread, including the initial issue submission, for this request, not just the latest update. Category: Windows version Group: 1.0.X Status: Open Resolution: None Priority: 5 Private: No Submitted By: kang (kangbooboo) Assigned to: Peter Åstrand (astrand) Summary: Cursor tracking is laggy (using local cursor) Initial Comment: In some scenarios the local cursor tracking result in a "laggy" cursor position update, even when using the local cursor (Render cursor locally option). E.g.: Windows system => RDP client (RemoteDesktop) => Terminal Server => TigerVNC viewer => TigerVnc server (Linux host) Using TightVNC2.0+ does not show this issue with the local cursor, e.g.: Windows system => RDP client (RemoteDesktop) => Terminal Server => TightVNC 2 viewer => TigerVnc server (Linux host) They seem to have a more complicated detection of the cursor for frame buffer updates, I'm not sure if it's related. They also seem to use the system cursor for tracking, while TigerVNC seems to hide the system cursor when you enter the window buffer area and display another one (locally), this might also disturb RDP - I don't know, I wasn't able to figure it out. ---------------------------------------------------------------------- >Comment By: Pierre Ossman (cendossm) Date: 2011-10-24 14:53 Message: I've seen something like this now and then. It seems to be a RDP limitation where it cannot transfer some cursors to the RDP client and falls back to server side rendering. Hence the lagging is in RDP, not VNC. Not sure we can do much without figuring out why we trigger this RDP fallback. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=1126848&aid=3105279&group_id=254363 ------------------------------------------------------------------------------ The demand for IT networking professionals continues to grow, and the demand for specialized networking skills is growing even more rapidly.
