Hi,
I am happy to hear that you solve the issue.
I am also sorry to say i can not search the bug
report, and never submit the patch with my sloth.

Hi Xiong,
My platform is WebKiton gtk+directfb. I am noticing that the issue is still
present in the current Webkit nightly R-44111 build. I saw your sugested
patch :
In function ChromeClient::scroll()
// gdk_window_move_region(window, moveRegion, delta.width(),
delta.height());
// gdk_region_offset(moveRegion, delta.width(), delta.height());
gdk_window_move_region(window, moveRegion, moveRect.width,
moveRect.height);
gdk_region_offset(moveRegion, moveRect.width, moveRect.height);
After applying it, I am not finding the scroll deficiency issue.
I wish to know if this fix is working, why is it not landed yet. What is
the plan for this bug.
What is the bug number for Gtk+Directfb platform.
Thanks and regards,
Srinivas Rao.M http://msrinirao.blogspot.com

Hi Frank
I am working on gtk+directfb and Brent working on Window+cairo, and
you ?
As you see, Brent and i have two separate bugs, because the
workarounds he described
do not help me.
For now, i have resolved the problem in my platform.
The reason why the screen display confusion is that GDK do not refresh
the
overlapping region when scrolling.
So, change the codes as following:
In function ChromeClient::scroll()
// gdk_window_move_region(window, moveRegion, delta.width(),
delta.height());
// gdk_region_offset(moveRegion, delta.width(), delta.height());
gdk_window_move_region(window, moveRegion, moveRect.width,
moveRect.height);
gdk_region_offset(moveRegion, moveRect.width, moveRect.height);
After do that, the problem was gone, at least in my
platform(Gtk+directfb).
Good luck.

Hi guys
Yesterday I wrote that I had solved the problem - at least on my machine.
Well, I was wrong. Apparently the redraw-problem only exists in
release-mode.
Could you please tell me what you have done to circumvent this problem?
You have talked about both commenting out code and doing something with the
... background..? Whatever it is I cannot find it in the mailing list, so I
would really appreciate if you could enlighten me. And do you know if this
has been reported as a bug? Can't seem to find that either...
Thanks in advance!
Frank

Brent,
In my platform, all the hack as you metioned are valueless.
Bad news to me.
Now, i only have a clue on cario for the scroll problem.
I think we may have two separate (but perhaps related) bugs, because
the workarounds I described do not help your problem. Furthermore,
the change you suggested (comment out the if (contentChanged) test
in ChromeClient::repaint ()) does not resolve my problem, while it
does fix yours.
Thanks,
