Hi Chris,
This is a common issue related to graphics card incompatibilities. There are a couple reasons you might see this. The Spike software for certain rendering modes requires the GPU to support OpenGL 2.0 or greater. You will see this issue with either an older GPU that does not support it or sometimes with a newer GPU that might have outdated drivers or drivers that have issues providing this functionality(rare).
Can you let me know what type of PC you are using? Preferrable make/model/CPU model and the GPU model(which you can usually find in the device manager under the display adapters).
I look forward to your response.
Regards,
Andrew
