Tint2 not behaving on edges

I’m trying to add tint2 to my fvwm setup, aligned on the left edge of the screen, but it is placed a few pixels offset from the edge.

Here is the config line for tint2 in my .fvwm2rc:

Style "tint2" !Title, !Handles, !borders, StaysOnTop, EWMHIgnoreStrutHints, Sticky, EWMHPlacementIgnoreWorkingArea, NeverFocus, WindowListSkip,

How do I make tint2 behave?

Just for information - aussieevil is talking about this program here]https://gitlab.com/o9000/tint2/wikis/home[/url]

I would suspect that the mistake is on the side of tint2 rather than FVWM. In the FAQ of that program they mention a similar problem with OpenBox. One workaround seems to be the configuration option »panel_layer = top« in ».tint2rc«.
Have you tried asking the guys there?
