Graphics artefacts appearing on Google pages (Win7 x64, v. 0.5.11)

[Oleg Dozorov]

On some Google and Google account-related pages scrollbars' and page fragments' particular self-overlaying stamps are trailing along the page canvas. A sample screenshot is attached here.
(I also once noticed the same artefacts whet I tried to move some windows above Midori when Midori was indicating Facebook page, but I never saw such thing later on Facebook).

(Here goes the about:version info for my case

Version numbers in brackets show the version used at runtime.

It may be due to that outdated webkit version.

I have a file named "libwebkitgtk-3.0-0.dll" in my Midori's "\bin" folder... O_o.. Why does about:version say that it is "1.10.1"??
(Perhaps, all these bugs happen to Windows Midori users only?)

Hello.
The bug still exist in version 5.11. The machine and OS are the same as before.
Here is one more screenshot :)
