Is there a setting for hiding window borders/edges when maximized?

[azcn2503]

Hi all,

One thing holding me back from using picom regularly is this very "first world problem" that causes me to inadvertently resize a window instead of scroll it, due to the scrollbar and window border being interactive at the same time. I spend an awful lot of time dragging scrollbars from the screen edge, but with picom I end up accidentally resizing windows.

I notice that XFCE's own compositor has the option to hide window borders when a window is maximized (also works when a window is snapped to the edge of the screen), and Mutter behaves in the same way.

I couldn't find a configuration option for this in my picom.conf. I am hoping that somebody can point me in the right direction. Or, if it doesn't exist yet, then I'd be happy to vote on an issue, if that's a thing!

Many thanks in advance.

I am not sure whether I understand you correctly but window borders are a WM thing. Window decorations (like borders) are added and managed by the window manager.
Does xfwm not offer said option when using an external compositor?

xfwm4 does offer this option, and it works regardless of whether or not its own compositor is active, because as you said, window borders are a WM thing.

It is why I like fvwm. It have no GUI for its configuration, but as fvwm can be seen as a toolkit for the Xlib, I can configure it as I want, the only limitation being my imagination and my time.
