I never experienced a single client crash so far, for what it matters.
I've had a handful, but they were all in "busy" areas and I suspect my now quite old graphics card (R9 390X... it was cool once) doesn't help. And keyboard polling can be a bit slow so I've learnt to hold e.g. N or SPACE down until it responds.
