Lockup bug in VLC and Firefox

During the last major update VLC and Firefox a lock up bug occurs where using both Applications together cause the System to lock up. At first I was thinking the Hardware issue. Now this only happens when using said apps at the time.

Due to using a 30" 2560x1600p Display, I can size both Firefox and VLC windows where FF is the main one and VLC is to the left side and smaller and often two or three.

Now my Computer is locking up depending on which Codec/File Format I’m playing.

How do I fix this? Wait for the next update to both program? BTW I try not to install anything from the AUR unless I need to and I know I can trust the package.

Don’t know if something I install is the actual cause.
