The main symptom is that scrolling in e.g. Firefox or Excel does not stop immediately after releasing the mouse button or the cursor keys but instead continues to scroll for several seconds.
In 1.3.x the scrolling stops as soon as you release the mouse button or key.
It is more obvious when you:
- have a slower client computer (old thin client or VIA chipset with e.g. 533 MHz or less) and
- the window of the application that scrolls is bigger (e.g. fullscreen 1280x1024)
The rdesktop versions were built using standard options except prefix (/opt/rdesktop/1.x.y) and sound set to OSS.
The command line is
/opt/rdesktop/1.x.y/bin/rdesktop -K -D -N -r sound:local -k de -g 1280x1024 -a 16 <SERVER>
P.S.: the same happens with Citrix ICA, but there is a configuration parameter: http://support.citrix.com/article/CTX105010
