Lemur resize crash

Hi just tested a bit around with lemur, and noticed that it tends to crash, if the window is resized.
Is a resizing window out of the scope of Lemur or is this a bug?

It’s a bug. JME provides no easy way to detect a resize so a lot of my code is “waiting for a solution” in this case.

Sorry for the trouble. I could probably try to fix it.

hm in the jfx bridge was just a if (! oldsize in update :slight_smile:
Surely not ideal, but if its stupid but works it’s not that stupid :slight_smile:
anyway the reshape method might be another working way to get this.

reshape() is on Application. I could register a dummy scene processor but really there should be something better.
