SUMMARY
When connected to KRDP session from Windows RDP client, KRDP application uses
system ram until full. Disconnecting RDP session stops usage but does not let
it go (ram).


STEPS TO REPRODUCE
1. Install of KRDP
2. Add user to KDE KRDP settings
3. Enable KRDP
4. Connect to host using Windows RDP Client
5. Log into system
6. Monitor system ram usage increase, more updates on screen faster ram fills.


OBSERVED RESULT
System RAM is used until Kernel closes RDP session due to memory usage and
kills KRDP pid, freeing up memory.

EXPECTED RESULT
KRDP should not keep increasing RAM usage.
