[Qt-interest] qtwebkit 4.5 flash plugin bug

qtwebkit 4.5 loads cpu by 40-70% when flash plugin enabled and
web-page with flash elements loaded (on windows).


I have a problem - Every page that qtwebkit shows has some adobe flash
plugin elements. And every page that has flash overloads cpu up to
40-70% while playing. Non-flash web-pages dont consume that much(I
would say not at all).

I tested on demo browser that ships with qt 4.5 and it also has the
same problem. As I drill down into process details of my application
or demo browser, I see that "Page Fault Delta" is almost always
30,000-60,000 every second. I dont see such big Page Fault Delta on
other browsers(firefox,apple safari,internet explorer). And every time
I go to a web-page containing flash it jumps quickly to 30,000-60,000
again. I tested on 5 other computers in our office with different
flash player versions(I tried 8th,9th,10th versions of adobe flash
player). but No luck! I guess this "bug" is only on ms windows.

I would appreciate any comment or advice regarding this issue.

WBR,
