Everything that related in Bitmap layer become big black blocks

Hi there

For some reason, the bitmap layer in Storyboard Pro 5.5.1.
become Black box and everything I draw become Black Box

All Thumbnails display are fine
Vector layers are fine as well

Just the bitmap that causes the problem
I reinstalled STBP 5.5.1 from scratch. Still, have a problem.

People said it because the system was using the integrated Intel card instead of the graphics card to render Toon Boom,
but how can I fix this problem?

You can add or edit program profile settings in the Nvidia and control panel, try with the settings there.

I don’t know about the Intel control panel since it seems I don’t have it installed, but as far as I can remember, you can control which software used which graphic card from there.
