Inconsistent screen redraw when scrolling in Chromium

[Aren Cambre]

When I scroll in Chromium, I get inconsistent screen redraws.

Attached is a PNG that demonstrates the problem. In that case, I scrolled up some. Notice how the banner image shows three times.

Occasionally, when I switch between tabs, portions of both tabs will be interleaved in horizontal stripes.

I can usually fix an inconsistent screen redraw if I take the Chromium window and move it around.

This seems to have started with a 14.04 guest when I upgraded VirtualBox and the guest extensions in September or October. I cannot remember the exact timeline. I installed a fresh copy of 14.10 yesterday (that's where the PNG comes from), and the same problem is happening.

I have 3D acceleration enabled and 128MB video memory. Host is Windows 8.1 x64.

I've also attached console warnings that appear when starting Chromium from the terminal window.

Correction: I had to upload a JPG instead of a PNG because the attachment size limit is tiny.

I confirm this as well, and not just when using Chromium, but Firefox, Sublime Text, gvim and the shell, especially when using vim inside it. Moving the affected window or even taking a screenshot within the guest causes a redraw and the corruption goes away.

I definitely confirm this! Tried adding --blacklist-accelerated-compositing, it does kinda work. The "tearing" occurs at multiple locations, for instance as I'm typing this comment, every once in a while the character I've just typed does not appear until I type in another character. The same goes for the omnibar.

This problem can be seen in other places like system settings window redraw etc. but most evident in Chrome & Chromium.

I'm on Ubuntu 14.04 LTS, 6GB RAM, 128MB Video RAM, 3d accelerated.

Guest Additions is 4.3.26, VBox itself is 4.3.12 r93733
