Might be related to #361 and #246, something to with how the hardware renderers having some timing differences relative to the software renderer.

Seems to be fixed in build 0.9.44.1 a264b2b dated 7-17-2019 running on latest Retroarch win x64 nightly build with same date. Thanks alot.

Edit - It seems to be fixed for the most part, however there are still very infrequent frame drops/stuttering mainly when the tutorial wizard guy "Lorock" appears from his floating hat. But it doesn't happen every single time he appears, only sometimes. Hope this helps but I'm not complaining too much because at least the game is playable again.

@pabloa2 Hi pabloa2, I realize this is an old issue but I've been trying to diagnose some similar issues from other users regarding frame drops on specific animations.

Do you remember which version of the hardware renderer you were running (OpenGL or Vulkan) and what GPU hardware were you running this on?
