I've had this issue with multiple versions of Inkscape on Linux for the past two years. When I select a line, and go to "Stroke style -> Markers", there is a dropdown menu with many arrowhead styles to choose from. Initially, all the arrowheads in the menu are shown in black. However, after editing the document for some time involving colored objects, the dropbdown menu starts acquiring colored versions of arrowheads. This makes the menu longer - the same arrowhead may appear in different colors. However, it doesn't matter which version I choose - the color will not actually appear on the line that I'm editing.

I'm not interested in using arrowheads with colors different from the color of the arrow body, so my main issue is that the menu is getting cluttered for no good reason. Has anyone encountered this problem?

Never happened to me: can you upload an example file please? Thanks

Please see the picture attached here (rightmost part, where the dropdown menu somehow also extended upwards to block parts of the side panel). Sorry for the phone photo, since I cannot open the screenshot app without making the dropdown menu disappear from Inkscape.

Here's how I reproduce the bug on my computer: 1. open Inkscape. 2. Draw a line, set the stroke color to red, and choose an arrowhead from "Stroke style -> Markers". 3. Draw another line, set the stroke color to blue, and choose an arrowhead again. 3. Draw a third line, keep the stroke color as black (original), and go to "Stroke style -> Markers". Now there is a blue arrow and red arrow for me to choose from, beside the usual arrow styles!

P.S. my Inkscape version is 1.0.2, but I've had this problem since pre-1.0.

I believe the "blue"+"red" in the first section (there's a divider line) are the "last used" ones which don't appear in the latest alpha to my surprise. I won't call it a feature to be honest.

You can find additional settings under Preferences->Behavior->Markers.
