Known issues with xrdp 0.9.1 - neutrinolabs/xrdp GitHub Wiki

Support for "noorders" clients is not enabled by default. Use --enable-painter flag to configure to enable it. Without that option, Android clients and Parallels client for Mac OS would not work.

Output fastpath is not working correctly, which affects Parallels clients. Workaround - replace use_fastpath=both with use_fastpath=input in xrdp.ini. Fixed in "devel" branch.

The TLS certificate is not compatible with MS RDP client for iOS. Fixed in "devel" branch.

There is no PAM configuration file for OpenSUSE. The generic file that is installed is not OpenSUSE compatible.
