VLC doesn't maximize properly - blue frames

[aus9]

Hi

screenshots first
/home/yourname/Pictures

(2) There are different ways of maximising VLC and am not sure which method you used so let me reveal mine without screenshots

VLC open  and use the maximum button leaves you with a frame similar to the frame for your file manager......I call this NORMAL MAX Screen

Next press or toggle F11 again and again .....removes the frame but leaves you with controls...or back to NORMAL

Next fifth button from LH side is the max screen....to the left of the equalizer button
----pressing it will max with no frames and no controls

Next hover the mouse near bottom edge bring back up a smaller control panel and you can then toggle the button again to bring back you to NORMAL MAX screen

let me know if you understood any of that.

PS I use mtpaint to take screenshots as I can then crop resize and convert etc but I won't attempt to do this until I see what you understand of above.
mtpaint can take a time delayed shot which helps if I need to hover over a control etc.
