4 Subject: [PATCH] xclearwin clears the window |
|
5 |
|
6 When an OCS sequence was used to change the bg color, the borders where |
|
7 dirty. This simple patch just clears the window before the redraw of the |
|
8 terminal when the bg color has been changed. This is apparently enough |
|
9 and seams to be very smooth. There was a TODO comment for it on the st.c |
|
10 file, which I removed. |
