Two issues here:
1. The repeller's shield doesn't seem to render, only the rune particles that are projected from it.
2. When you go into either F5 third-person perspective (or the F1 gui-hiding perspective) while a repeller is active and rendered, your perspective turns to a blank white.

Pictures:

Yes, it's likely that this is caused by an incompatibility with your Intel graphics card. Could you send us your client log?

I am experiencing the same bug but in version 3.7.3, I can send you my client log.

That GPU might not support the shaders used, just a guess.
