One question, when that happens you are using the PC via Battery or connected to power?
I got the same thing when I try to edit photos in my GL551JW (HDR Pro) on Adobe Photoshop or when using Adobe Premiere but only when the PC is running by battery.
The reason for what I've found is because of the configurations of the Intel Video Card (that Adobe apps use to some editing effects) that it's configured as Max Battery Performance instead of Max Graphic Performance (or something the like in the Intel Options).
Using the charger everything goes to Max Performance. What you need to do is change that options in the Power Options when in Battery (don't change from Balanced Profile to Max Performance Profile because in battery all the profiles in the Intel options are for Max Battery).
I'd love if it were a Power4Gear that controlled that in the GL551JW but it let's the Windows 8.1 controls it.
