Since at least Sep 8, I've been getting compositing glitches. They seem to get worse the longer a browser session is going; they may specifically be set off by display geometry changing (they're really bad once I wake my PC's monitors from sleep). When I restart Firefox to install an update, they're gone for at least a few hours. At a given point when an area of a page repaints, some of the layers seem to be missing - fills, etc. I also see flickering when a large image is progressively loading - the background behind it flickers, the image flickers, etc. Causing an area to repaint makes the glitches go away, but if it isn't repainted they stay indefinitely. This happens on basically every page I visit, but it's worse on pages with complex layouts. This session has been going for a couple days and my monitors were off overnight; now the glitches are so bad that when I resize the text field in Bugzilla the background constantly glitches between white and silver.

Forcing a driver reset ('nvidiainspector -restartDisplayDriver' in this case, though there are other ways) fixes the compositor, at least temporarily. Unfortunately it breaks other things in the UI, like permanently discarding the contents of some chrome bitmaps. I think I already filed a bug about the way FF handles driver resets.

Hrm, this is pretty bizarre. Can you run a debug build and see if you get anything out of the ordinary on the debug console when this happens.

Is there a particular spot on the FTP I should get the build from?

This still happens, including on a new machine I built with a different geforce card (980Ti). Latest windows 10 x64, latest geforce drivers, developer edition x64. Also, somehow these compositor glitches can be retained (!!!!) in pdf.js's cached version of pages of a document. Saw it happen in a slide deck PDF; one of the pages rendered with a compositor glitch and the glitch remained in that single page of the PDF until it was dropped from pdf.js's cache.

The compositor issues seem to have become worse, because now not only are individual chunks of layers rendering wrong but they're rendering in the wrong places sometimes.

The glitches seem to especially impact pages with many layers, like the lightboxes twitter started using recently. In this short video clip you can see things go haywire pretty badly when I open a lightbox.

I also suffer from the same problem, most often on Twitter and Hangouts. I'm on Windows 10 x64, Stable channel 64-bit, geforce GTX 970.
