Description

Hello, 

I'am having an issue on Windows 7 RDP targets: when i open LibreOffice Writer it causes an  immediate disconnect. If i try to reconnect immediately it fails, it will only be possible to reconnect after a few minutes. Connecting via windows RDP client works and makes a guacamole session work again.

I've met this issue since 1.2.0.

I've disabled all (glyphe, offscreen, bitmap) caches within src/protocols/rdp/settings.c file. It did not help.

You can find guacd logs of the bugging moment. It seems to be related to some Brush Cache.

Thanks for your help

Regards
