Created attachment 74180 [details] image in editing Hi, I am attaching a couple of screenshots showing rendering artifacts with libreoffice. These are obtained on a DELL E6500 with mobile4 (gen4) graphics card, kubuntu 12.10 64bit and updated kernel and graphic drivers. Currently on linux 3.7.6 (from the ubuntu mainline ppa), xorg-server-video-intel git snapshot of 1 feb (commit cf0576...), mesa git snapshot of 22 gen, libdrm git snapshot of 28 jan. Issue happens both with compositing on and off. I do not know when or why this started to appear. I see it both with libreoffice 3.6 and with 4.0RC3. The fact is that recent libreoffice tries to mark with a dense mesh pattern the text boxes that are under editing. When the areas being marked are wide, strange things start to appear. The mesh is corrupted and so are the bitmap images that appear in the page. Thanks for looking at them.

Forgot to say that scrolling up and down eventually fixes the rendering.

Created attachment 74184 [details] image in editing No, it is not the libreoffice mesh, nor the presence of text. It is just the large image. If I take a large image and paste it into an empty drawing, at first it looks fine. If I then try to move it aroudn (select it, press the arrow keys) at each movement step I see the artifacts changing. Passing the mouse over the image does not change anything. I do not think I was seeing anything like that back in October. when the dup bug was submitted, I would have noticed it.
