I am currently using Cabbage 2.9.193, but I noticed this problem several months ago on Cabbage 2.9.0 as well. I never encountered this problem on Windows, and I have not tested MacOS. It hasn’t bothered me significantly, but I decided to post about it now. I double-checked to make sure there aren’t other topics about this, but maybe this is already a known slug. Any rslider widgets on Linux are missing their visual marker on the knob. Below I created a new effect plugin from the template and didn’t change any code. There should be a black marker on the rslider widget by default, but there is nothing. Specifying any other color with `markerColour` does not change anything. ![image](https://forum.cabbageaudio.com/uploads/default/original/2X/e/e0473d82c0740b3adee0895cc9b2fb99209bf2aa.png) Here is the file as well.

That’s weird. I regret to say that I don’t spend much time on Linux these days, but I can’t think why this would happen. I’ll take a look when next I at my Linux box.
