I am not sure if you mean that you found the delay bug, but the fix is not included in this release or if you mean it IS included in this release...
...in any case:
The focus issue appears to be worked out. I tried multiple times to cause mala to play the videos in the background while mame ran and I could not. Bravo!
...the delay, however, is still present. I THINK your post meant that you found the bug but the fix isn't implemented yet, which would explain why the delay is still there...but just in case you thought you squashed the bug...it's still there.
Thanks!
