User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.9; rv:33.0) Gecko/20100101 Firefox/33.0
Build ID: 20141105223254
Steps to reproduce:
1. Create a new window (Cmd-n)
2. Zoom the window to full screen (Window menu > Zoom)
3. Drag the window offscreen to the left.
4. Resize the window by clicking and dragging the right edge.
Actual results:
The expanded area of the window shown after the window is resized draws black.
The title bar of the window draws garbage; title bar buttons are drawn multiple times and with lines through them.
See attached screenshot.
Expected results:
Window just gets bigger and draws all window controls correctly.
If I restart the app in Safe Mode, the drawing bug doesn't occur.
If I disable all plugins and extensions, a slightly different drawing bug happens. Instead of black pixels being drawn, I see multiple instances of the Zoom button in the window title bar. See attachment.
My apologies, I don't have the attachment mentioned in my previous comment and I can't get that particular variation of the bug to happen. I see black space and badly drawn window title bar.

The safemode also disables the graphic hardware acceleration.
Disable the hwa under options/advanced/general/[]Use hardware acceleration... (Firefox restart could be required)
Component: Untriaged → Graphics
Product: Firefox → Core
When I turn off Hardware Acceleration, I no longer see the garbage drawing. However, I now see the previously mentioned bug where multiple copies of the Zoom icon are drawn. See attachment.
