This is true for the legacy GDI mode of operation. The new version has less bugs but is a bit slower in this mode. (mostly the newly introduced input validation that is much more costly in this mode to prevent remote exploitability) If you connect to anything newer than windows XP/Vista you should just add /rfx /gfx:avc444 /network:auto to your command line. that activates the newer RFX or GFX drawing paths which should be much faster. (if the server does not support it is ignored, so just do it anyway ;)) > Here are some details on my usage scenario: > I am using freerdp on self-made thin clients based on Ubuntu.
