We use OpenGL (Open Graphics Library) for graphics rendering in our products. It is used to interact with your graphics processing unit (GPU) to achieve hardware-accelerated rendering enabling more processing power from the CPU to be focused on audio rendering.
In certain instances GPU Acceleration can cause some issues if not properly supported on your computer, it can cause the interface to appear black/blank. To turn it off click the menu icon in the top right corner of your plug-in and select "UI Scaling & Settings". Click the checkbox in front of "Use GPU acceleration" to disable it. You need to restart the plug-in for the changes to take effect.
