Comment 21 for bug 940603

I get what might be a variant of this bug. A white window or box appears covering the page display area but none of the UI in chromium.

My problem seems unrelated to either notifications or Flash; for example, it can appear when using the "Open Image in New Tab" context menu item. It always appears on the initial page load.

Despite the white box, I can Alt+Click to drag windows out of the covered area and interact with things underneath; they're just not visible.

Logging out, then back in is the only way to make it disappear.

Attaching two screenshots.
