When setting marks in swayfx, the background is not fully apply in the titlebar. Here are 2 partial screenshots to better see the issue :

one fix i found is to not update the clippping are in the mark block if there is a title text. Im not skill enough in the swayfx internals to know if this is the correct fix, but it works and i didnt saw any glitches in any container mode, tabbed, stacked, split, floating ...

here is the patch im using :

Interestingly this is only with one char marks

Looks like marks also have an implication wrt transparency of the title text:
