Three cheers for anonymous AMD engineer that fixed OpenCL driver bug

My app makes very heavy use of OpenCL events.

For the longest time, the app was unstable - seemingly there was a race condition where

event callbacks sometimes would not get called, causing my app to stop working.

Now, with update 18.5.1 on Windows,  this problem has miraculously gone away. Everything is rock solid.

And I can run the app for a long time with no drop in performance

So, whoever you are and whatever you did, thank you!

Unfortunately, driver 18.6.1 has made my application completely unusable.

Callbacks are not firing at all.

Unfortunately, very hard to create a reproducer for this.
