You might not know it, but you can not only switch transitions on or off, but also set the specific transition WPI uses.

In the tooltip-style parameter 21 says 51 in the example config.

51 stands for "random" - so the transition would change.

if you set it to a value lower than 51, the transition style will be fixed to a siingle type. Play around with it.

i use it

suggest to try with transition 24 with a 0.5 timing
