Firefox window sometimes does not redraw after I close a tab
This started a while ago and has persisted through multiple updates of Firefox and my display drivers. It's straightforward: sometimes when I close a tab (via keyboard or mouse) Firefox does not redraw its window and I am left looking at a "ghost" version of the tab.
If I move my mouse over the window I can see it responding to links in the tab that Firefox has switched to, but the display will not update until I do something to trigger the browser to redraw its whole window (e.g. resizing it).
I am using Firefox 36 beta and have a GTX 560 Ti graphics card with the latest Nvidia drivers. As I mentioned above though, this issue has been around for a while and is not specific to the version of Firefox (I don't normally use betas) or drivers I am currently using. I don't have problems in any other program.
Has anyone else experienced this?

You can try to disable OMTC and leave hardware acceleration in Firefox enabled.
- about:config page: layers.offmainthreadcomposition.enabled = false
You can open the about:config page via the location/address bar. You can accept the warning and click "I'll be careful" to continue.
Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.
- Switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance
- Do NOT click the Reset button on the Safe Mode start window
