The page uses a small background image (only 1x4 pixels) And that makes mozilla really slow, the page works ok in netscape 4.51 but when I try to scroll it in mozilla the program can freeze for 1-2 secounds on my k6-200 Mhz. But it works ok without the background image. http://members.linuxstart.com/~jonas/urban/ / Jonas Borgström

Don, I am reassigning this bug to you since you have been looking into DDB vs. DIB performance on WIN32.

Added some Tiling code, recursively doubles the size of the background tile until it can do about 4 big blits.

Reopening. This same optimization needs to be applied to table cell background as well. See this URL for an example: http://messenger.netscape.com/bookmark/4_5/messengerstart.html this is currently being used as the default page in messenger.
