I access my kubuntu machine remotely quite a lot and have been using x11vnc with the -ncache option to grat satisfaction
After upgrading to 14.04, the client window scrolls down almost every time I bring my mouse to the bottom of the screen, showing garbage below the remote screen.
As far as I understand it, this is an artifact of using -ncache 10 in the x11vnc command line. -ncache allows the client to store some bitmaps locally so that they don't have to be resent from the server, making the experience much more pleasant over remote connections, but it does it by reserving a area much larger than the screen to put that bitmap info.
So what's happening is that my client (UltraVNC viewer on windows) scrolls down into that area reserved for bitmap caching.
So while it is a documented issue with using -nchache, something changed after I installed 14.04 that causes it to scroll down as I approach the bottom of the screen. previously I would only see the cache area if I dragged the mouse below the screen, which rarely happened.
Any idea why 14.04 is causing the screen to scroll down as I approach the bottom?
FYI, here's how I start x11vnc:
