Graphical artifacts with remmina/xfreerdp

[urusha]

There are several cases when graphical artifacts appears with xfreerdp/remmina on ubuntu 12.04:

1) Use xfreerdp with 15bit color depth:
# xfreerdp --sec rdp -a 15 srvaddr
See screenshot-1 (w2k3), screenshot-1-2 (w2k8). Disabling bitmap cache fixes it:
# xfreerdp --sec rdp -a 15 --no-bmp-cache srvaddr

remmina isn't affected. Seems it doesn't use bitmap caching (and has no such option) or use some workaround?

2) Use remmina/xfreerdp with 'Remote control' feature (from 'terminal services manager') with client which session has different (higher/lower) color depth than your session. See screenshot-2. Enabling/disabling bitmap caching doesn't help.

3) Use remmina with 'Remote control' feature (from 'terminal services manager') with client which session has higher resolution than yours. Facing white space on the right and bottom side of the screen, it's clickable (you can run 'start' menu), but it's always white. See screenshot-3. xfreerdp works fine, that's remmina issue only.

Issue 1 is more strange than critical, while issues 2,3 make rdp 'remote control' feature (one of the main features) mostly unusable. Please, fix it.

Could be a possible fix.

To bad the daily build on Freerdp ppa are broken atm.
Will give a sign if they are ok again, then you can test it.

urusha, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue with the latest version of remmina in Precise, or a later version of Ubuntu?

If so, please execute the following via a terminal as it will gather necessary debugging information:
apport-collect 1006300

As well, please provide click-for-click steps to reproduce this problem, as well as the OS you were trying to remote into.

Thank you for your understanding.
