So is there like a delay in Malzahar's R suppression or what? It always happens later than it should

When going up against a , whenever I click my R onto her just as she uses her E, but BEFORE she uses her W (stun), I see my laser hit her, and her W's animation goes off anyways even though I was supposedly staring her down during her E's animation. The result? I get stunned and my R goes on cooldown and she begins to do to what melee champions to do him and . Same goes for other champions with disruption abilities, their CC will always go off even if I had my R hit them before they can use it.

And in that same vein, I also get a lot of instances where I use my R on my opponent while they're still on my W, but for some reason the opponent always moves just outside of my W's AoE before they stop moving for real, even though I was already R-ing them while still atop my W.

So what's up with that.** Is there like an unmentioned delay before the suppression from his R take place or what?**

If there is a delay that happens before an opponent even gets suppressed........then why wasn't it mentioned in any Champion Spotlight or Tooltips?!?! You want Malzahar players to not be even rare than a Shiny Clefairy? Then inform players of nitty gritty intricacies with their kits that would repeatedly save their lives! If there isn't a delay before the suppression, then...........................................this may be a very commonly occurring Malz glitch that's been around for a long time.
