screenshot of graphical corruption with gtk3 VCL plugin

The gtk3 VCL plugin in libreoffice-3.5.0.0 has severe problems making it basically unusable. If libreoffice is built with --enable-gtk3 and launched with SAL_USE_VCLPLUGIN=gtk3, then:

1. (as reported in https://bugs.gentoo.org/show_bug.cgi?id=392939) copy/paste to all non-libreoffice applications fails. In other words: text selected in libreoffice-3.5.0.0 writer will not middle-click-paste in any other application (but will middle-click-paste in libreoffice itself). Text selected in any other application will middle-click-paste in any application except for libreoffice. Text copied using Ctrl-C or Edit→Copy in libreoffice-3.5.0.0 writer will not paste using Ctrl-V or Edit→Paste in any other application (but will paste in libreoffice itself). Text copied using Ctrl-C or Edit→Copy in any other application will paste in any application except for libreoffice.

2. (as reported in https://bugs.gentoo.org/show_bug.cgi?id=392943) 3.5.0.0 writer suffers from severe graphical corruption when using the scroll bar to scroll up or down. Blocks of text become garbled, random black lines occasionally appear, and even UI elements (such as the scroll bar itself) sometimes become corrupted. Sample screenshot is attached.

I am seeing these bugs on two different amd64 Gentoo systems running gnome-3.2 with gtk+-3.2.2; one with binary nvidia drivers, the other with open-source intel graphics.

Note: these problems do not occur if libreoffice is launched with SAL_USE_VCLPLUGIN=gtk

I know these problems with WIN when soft scrolling is activated, is that really new with 3.5 Beta or with what Version did you observe that problem the first time?

The copy/paste problem:
* 3.4.1-3.4.4, gtk vcl plugin: did not occur.
* 3.5 beta, gtk vcl pluguin: does not occur.
* 3.5 beta, gtk3 vcl plugin: occurs 100% of the time.

Scrolling graphical corruption problem:
* 3.4.1-3.4.4, gtk vcl plugin: occurred rarely, affected the document text only.
* 3.5 beta, gtk vcl plugin: does not occur.
* 3.5 beta, gtk3 vcl plugin: occurs 100% of the time, affects both document text and UI elements like scroll bars.

Is this bug still valid / reproducible with the latest LO release from http://www.libreoffice.org/download/ ?

Could you please attach the document in question? That would help speed up the process of confirming and successively fixing this bug a lot. Thanks :)
