[FFmpeg-devel] [PATCH 2/3] kmsgrab: Do not require the modifier to stay constant.

[Bas Nieuwenhuizen]

As we get a new set of objects each frame anyway, we
do not gain anything by keeping the modifier constant.

This helps with capturing when switching your setup a
bit, e.g. from ingame to desktop or from X11 to wayland.
