[BSplayer 1.00.803]: Great improvement, a few bugs remain.

[Dracula]

Same deal: double clicking for full-screen-switch decreases the volume by 4%, BUT only by going from full screen -> windowed, not the other way around.

This is because a double-click is interpreted as "left click + mousewheel down" (you can check that when assigning hotkeys to actions). And by default, the "left-click + mousewheel down" is assigned to decrease volume...

You can simply remove this assignment, and the volume won't be affected by double-click anymore.
However, still it is a bug.... ;)
