raser1 It seems that if you increase of decrease it by a little amount (like 5% or something) the slider pops back in it's old position after 1 or 2 seconds.
However if you decrease or increase it by a large amount (around 10/15% or more) the slider stays in position like expected. So the issue seems to only occur when changing the slider by a little amount. Should be easily reproducible.
If anyone experiences this bug, the workaround is to first set the slider to something far away from the value you want. Let's say you want to set the max value to 90 and it's currently on 85, you first got to set it to something like 50 or 60 and then slide it to 85. Hope that makes sense lol.
