I have this problem with SiN Gold from GOG, the original demo version doesn't
contain videos to reproduce it.

The game starts with a still image which looks like a loading screen displayed
@640x480 then the screen flashes rapidly as the game changes resolution a few
times, then the intro video begins to play @1440x900, but the video is frozen
with the first frame from the video (music keeps playing).
If I press and hold a mouse button or a key then the video resumes playing
normally. As soon as I release the mouse button/key the video is frozen again.

Reproducible in fullscreen and virtual desktop mode as well.

The problem is present since
