Feature request: option to disallow the rounded corners on maximized fullscreen windows.

[domichel]

I like very much the corner-radius feature. Using fvwm and fvwm-crystal, I can put any window into a maximized fullscreen mode (and back) with a single key binding press, and I dislike the rounded corners in the FS case.

Also, as the main fvwm-crystal developer, I have no way to know which windows an user will put in FS.

It would be great if picom was not applying the corner-radius to the FS windows, or even better if it was a config option for that.

Thanks for the good software.

As fvwm is ewmh compliant, and fvwm-crystal is an ensemble of themes exercising fvwm, it is also ewmh compliant.

You must create a rule to do that:

rules = (
    {
        match = "_NET_WM_STATE@ = '_NET_WM_STATE_FULLSCREEN' || _NET_WM_STATE@ ^= '_NET_WM_STATE_MAXIMIZED'";
        corner-radius = 0;
    }
)
