When panel is maximized there are a few pixels of space in the eft and right edges of panel: Sample screenshot
When I want to hit menu icon I need to pay attention, which is not what I want. I’d like to be able just move mouse to the screen edge / corner and click to open menu.
i’m just saying it’s not supposed to be like that so you should report the bug.
one last thing to try is edit mode, then hover over the applications launcher section of the panel and make sure its’ shoved all the way into the corner.
