Description

The description of this issue was copied from GUAC-1068, an issue in the JIRA instance used by the Guacamole project prior to its acceptance into the Apache Incubator.

Comments, attachments, related issues, and history from prior to acceptance have not been copied and can be found instead at the original issue.

When using the terminal emulator via SSH or telnet, the background color of blank areas is not properly redrawn after it scrolls off the screen, including the background of the cursor.

To reproduce:

1. Run something that sets inverted color mode like top
2. Quit the program so it stops drawing to the terminal
3. Scroll up until the text with background color is no longer visible
4. Scroll back down - the background color will not be set for blank characters
