SubLab uses OpenGL by default to draw the interface.
Older graphics cards (Nvidia GeForce 9500 GT for example) and some onboard Intel graphics chips in Windows laptops (such as Mobile Intel 4 Series Express) can have trouble using the newer OpenGL.
If you are experiencing a blank interface like in the image below, here's what you can do.
Update your graphics card drivers
Check what graphics card is in your computer. Then visit the manufacturers site and update the drivers.
Make sure you're using the latest version of SubLab
You can disable openGL altogether - just make sure you have installed the latest version of SubLab. Find more info on the latest version of SubLab here.
Disable openGL
1. Once you've downloaded and installed the latest version of SubLab, navigate to the folder .../FAW/SubLab
Unless you created a custom filepath, you can find the files here:
PC: C:/Program Files/FAW/SubLab
macOS: /Library/ApplicationSupport/FAW/SubLab
2. Open the file settings.xml in a text editor - you'll see something like this:
3. Find the line opengl_disabled and change val="0" to val="1" like below.
4. Save the file and then launch SubLab. You should now be able to see the interface as normal - no more blank interface!
