Hmm. Is this usually happening when having a huge zoom level?

Not really. Like I said, sometimes I can "walk" the path and find where I
can insert or delete as normal. I do this at the same zoom level. It's like
the path got corrupted and I have to delete the corrupted part of the path
and rebuild it, then everything works fine again.

There is a funky problem there: for determining the closest point along
a bezier the bezier segment is approximated by line segments to a
certain precision. The precision used does not take the zoom level into
account. This is usually no problem, since it is < 1 pixel and "close
enough" for the usual zoom levels.

However there are corner cases in huge zoom levels, where the
(invisible) line approximation is off by a significant fraction of a
pixel, so that the net result is an active area disconnected from the
drawn bezier segment. You can verify this by searching on the "inside"
of the curved bezier segment for an active area.

I'd consider this a bug that might have been introduced when we
introduced cairo-based rendering for the tool graphics (earlier the
drawn path used the same line approximation as the detection code).

Probably a bit tricky to fix...


I'm wondering if my clipboard manager isn't screwing things up. I discovered
a problem within inkscape that is apparently affected by it and everything
works as it should when I turn it off.
Can you discern anything from this bug report that might affect gimp as

I will try disabling my clipman next time and repeat the copy+paste to see
what happens.
