Fixing VLC 'Bugs'
Step 1
Reset your Preference settings under the "General" tab, quit VLC and restart.
Step 2
Try deleting VLC's configuration file, which is located in your user directory.

For Windows XP users, VLC can be found in your C-Drive: C:\Documents and Settings%username%\Application Data\vlc\vlcrc

For Mac OSX Users: HOME/Library/Preferences/VLC

Download and re-launch VLC.

Step 3
Upgrade your video card from its manufacturer; for many, this is a free upgrade. Or, try disabling your video's overlay by clicking "Preferences/General/Video" and de-selecting "Overlay Video Output."

Step 4
Change your video "output module" by clicking "Preferences" and selecting "Video." Click "Output Modules" and try choosing a different option (VideoLan suggests trying the "DirectX video output," which claims to have helped many people who experience "purple video").

The player window is shifted to the right by 50% beyond the screen. Using the arrows it is possible to pull out the left side of the window by 2/3. The right frame of the window is not available (beyond the screen). Why is this so? What to do?

I just built a 12700K and VLC will no longer retain "always on top" as a preference and I have no idea why. I've never had this problem before. I've changed renderer, etc and looked for any option out of place which might cause this and cannot find any. Any help appreciated.
