How to Stop VLC from Blanking Screens in Full Screen Mode – MacOS, Multiple Monitors, VLC Media Player

Install Flash Game Maximizer Firefox plugin https://addons.mozilla.org/en-US/firefox/addon/9631, maximize your Firefox window and press F12.

Windows Console settings are kept in Registry (Start → Run → regedit), under the HKEY_CURRENT_USER\Console key¹.

• The default settings are under HKCU\Console itself. Make sure the FullScreen value is set to 0. If not, change it.
• Per-program settings are stored in sub-keys named according to the program's path. Look for an entry belonging to your compiler, fix it if necessary.
• You can just delete the entire HKEY_CURRENT_USER\console key (although you will lose the customizations you might have wanted to keep).

A trick you could try:

Start a long compile, and just after the full-screen switch press Pause on your keyboard to pause it, then Alt+Esc to minimize the window. Right-click on its button in the taskbar, choose Properties, then Options, and select Display Options → Window.

¹ In regedit, keys are the folders in the left-side tree, and values are items in the right-side list.
