I’m also having this issue. It seems I accidentally sized it too small and now can’t size it back up: making the plugin widget unusable. This is with the Collision Groups Editor.
Are there any updates on when this will be fixed? This is very annoying when trying to use the animation editor and closing and opening it to modify parts of the character. I have found that if you dock the widget to the side and bring it back out, it will allow you to resize it again.
This also happend to me i was following a car tutorial and i closed collision group editor then had to open it back and i couldnt resize hope this gets fixed soon!
I’m experiencing this bug as well while working on a settings window for my “camera light” plugin. This bothers me since I want to allow a small minimum size, while being able to resize it as big as it can fit my screen. Hopefully it is fixed soon.
