Package: rdesktop
Version: 1.8.3-1
Severity: important
Tags: patch
RDP needs the following fixes to work well connecting to Windows 10
1) Support passing DPI to Windows 10 RDP Server; Windows 10 lost support
for using the registry provided value in this case.
2) Support using the desktop manager provided cursor instead of the remote
machine cursor; in some determinstic scenarios the remote cursor is no good,
but this is borderline impossible to detect. The user will know what to do.
