After applying the following update, my login screen, when I come back from suspend mode, is not working properly. It does not let me login, and somehow shows what appears to be a fragments of an old frame buffer image that was on the video card before going to suspend mode.

If I put it back to suspend, and come back again everything is fine.

I noticed this behaviour after doing some system updating. Follows the update details:
