So, since the NVIDIA GTX 750 is not supported by Nouveau and the modesetting driver is used instead, I decided to try it out only to find out it has the exact same issue as Intel.
So, it not exactly rules out the possibility of a bug in mesa, but it is more likely to be a bug in the modesetting driver. Time to check out its code, but at least it is super easy to reproduce :)
