Is there a method to hide specific floating window's border by checking it's xprop and set it in rules?

I don't want the float border shows in some application like the file manager, beacuse it renders incorrectly.
Is there a method that I can write the rule to skip it? for example, a isborder option like issticky, isfloat, etc.

Yes there is the decoration hints patch that may work:

In this particular case it may also be an issue with the gtk theme, refer to:

I would say it's sooo cool! I just flip the DECORATION_HINTS_PATCH to 1 then re-make, and things gets normal! Thank you!!!
