No, because it only clears the bg of the newly exposed area, the part 
that wasn't "visible" before.
The bevel was on the "visible" part before, so it's not cleared.


+-------------+
|#===========#|
|"           "|

|#===========#|

when resizing, app_server only erases the hashed part:
+----------------+
|#===========#///|
|"           "///|
|"           "///|
|#===========#///|
+----------------+

Then BBox draws the bevel again:
+----------------+
|#==============#|
|"           "  "|
|"           "  "|
|#==============#|
+----------------+

and there is still garbage.
