Dock handle disappearing after altering size to full screen width or height

I have a dock view which I update the size to match the size of the users screen using system.perspective.alterDock.

When I open the dock it correctly resizes to the screen but when I close the dock to hide it the handles disappear?

It only happens if I resize the dock to full screen ,not if I resize the dock to 80% of the screen width or height.

Share all of your relevant scripts (including the one which closes the Dock).

Here is the onStartup script when the TrendDock is started up

system.perspective.alterDock('TrendDock', config=config)

Here is the script on the button which closes the dock


Okay fixed this by removing this from startup.

Created a viewport binding on the view and added a onChange script to update the docksize

Works as intended now
