I am designing an RF PCB in Altium and I have set rules for 75 ohm as well as 50 ohm impedance traces. The picture attached shows a particular 75 ohm traces with error markers. The trace width is as specified by the rule and the DRC check does not show any errors. When I reset the error markers the markers do not go away. As you can see the traces are not the problem since the markers are also showing up on component pads.
I appreciate any comments.
Are you sure it's a violation marker? Those default to bright green. What you have could just be display override color for that net's connections.
Is the * column for the net checked in the PCB control pane, like this one?
Un-check your net and it should then only color ratsnest wires and not all objects tied to that net.
Edit: clicking around a bit more it looks like this feature is called "display override" in case you want to search for it on the Altium Wiki.
If you are defining a particular rule for these primitives that go against global rules (eg. track width), these errors will actually remain highlighted unless you uncheck the "Online DRC" option.
