Copy/paste not (always) working from host to guest

[nopaste]

Copy paste sometimes works from host to guest, but then often stops working after a few hours of the VM running.

Copy paste from guest to host works.

Facing same problem here, copy and paste stops working at some point. Setting is correct: bidirectional.

The problem still exists. A temporary workaround is the following shell command:

ps aux | grep '[c]lipboard' | perl -ne '/([^[:digit:]]*)([[:digit:]]*)/; print "$2\n";' | xargs kill -TERM ; /usr/bin/VBoxClient --clipboard

I need to run this command after copying from Windows and before pasting to Linux. Then immediately the copy paste stops working again and I need to repeat the process.
