You have been subscribed to a public bug: The content of new tabs in Firefox is sometimes corrupt - the content is not drawn in the correct location or it's shifted/wrapped around in the current window. There can also be visual artifacts such as 'static' in certain parts of the window.
I use fullscreen windows almost exclusively, and I've seen the problem twice today when opening documents in a new tab in a fullscreen window. I don't know if the problem affects windows that are not fullscreen windows. This is a recent regression; it started around the time I upgraded from unity 6.4.0-0ubuntu4 to unity 6.4.0-0ubuntu6. See the attached screenshot for an example. I've blurred or redacted parts of the window. The multicolored static at the bottom right is part of the image, not something I've added. The big black rectangle is content I've redacted. Things to note in the screenshot: * There appear to be 5 distinct panes: left side, right side top, 'static', center bottom, right side bottom. Each contains different parts of the browser window. * Content in the bottom-right of the window is scaled down a lot compared to the rest of the content * Content in the bottom right pane might be from another tab - note that it's a Google Doc that includes the text, "All changes saved" in tiny letters. The content of the main tab is another Google Doc, which has different text in the same position: "Last edit was made <redacted>" When the FF window is in this state, a workaround is to take the window out of fullscreen mode; it redraws properly. The windows stays drawn properly if you make it fullscreen again. To reproduce: 1) Open a new tab Expected results: New tab is drawn properly Actual results: New tab is not drawn properly; it may be shifted/wrapped around the screen, and may have other visual artifacts.
