Right click context menu displayed as transparent
I'm on FF35 and I've started noticing this problem for the last 6 or 7 versions.
When I right click anywhere in the page in order to display the context menu, this is shown as transparent (only the lower and left side panel shadows are displayed). This problem usually occurs approximately 4 time out of 10 (see attached image):when this happens, it usually takes a few more repeated right clicks to finally display the menu correctly.
I already tried the following to no avail: 1) Change window theme: problem also happens with the default theme 2) Disabling hardware accelaration
Any other suggestions? Thanks Regards
Sergio

Hello,
Try Firefox Safe Mode to see if the problem goes away. Firefox Safe Mode is a troubleshooting mode that temporarily turns off hardware acceleration, resets some settings, and disables add-ons (extensions and themes).
If Firefox is open, you can restart in Firefox Safe Mode from the Help menu:
- Click the menu button
, click Help 
and select Restart with Add-ons Disabled.
If Firefox is not running, you can start Firefox in Safe Mode as follows:
- On Windows: Hold the Shift key when you open the Firefox desktop or Start menu shortcut.
- On Mac: Hold the option key while starting Firefox.
- On Linux: Quit Firefox, go to your Terminal and run firefox -safe-mode
(you may need to specify the Firefox installation path e.g. /usr/lib/firefox)
When the Firefox Safe Mode window appears, select "Start in Safe Mode".
If the issue is not present in Firefox Safe Mode, your problem is probably caused by an extension, theme, or hardware acceleration. Please follow the steps in the Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems article to find the cause.
To exit Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.
When you figure out what's causing your issues, please let us know. It might help others with the same problem.

You can try to disable hardware acceleration in Firefox.
- Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"
You need to close and restart Firefox after toggling this setting.

Hi cor-el, thanks for the suggestion but as mentioned in my post I had already tried that. Regards
Update It looks like the culprit was really hardware acceleration after all. I'm quite sure I tried disabling it and it did not fix the problem. I then tested the problem running FF in safe mode as suggested by Diego Victor and the issue was gone: I therefore thought that the cause was to be found in one of the extensions. Reverted to FF in normal mode, I found that the problem was still gone. Went to re-enable hardware acceleration and the problem re-appeared.
Thanks cor-el for having me try it twice :) Regards
Sergio

Hi Diego, thanks for the hints. Apparently the problem was caused by HW acceleration.
