Tint band drawing using ArcMap

Question

I installed ArcGIS 10 SP1 last week. My graphics card meets the spec and I'm up to date on drivers. I have a layer of parcels that are tint-banded in the MXD.

At some scales, straight lines that are the same color as the tint band shoot across the map. After this happens, the next, second, or third extent change crashes ArcMap (usually it's the 1st or 2nd). When I successfully change extent, I'll get a different set of straight lines.

In the image below, only two of the polygons are (or should be) tint-banded:

Has anyone else experienced this and know the cause? And does anyone have a solution (besides not using tint bands)?

I did a check/repair geometry, but the issue continues.

I was able to replicate the issue with US Counties: here's a layer package of the US Counties with a green tint band. As I zoom in/out, I experience the same issue.

Perhaps this is a result of the way I create the tint bands.

Answer 1

The problem appears to be caused, in part, by the complexity of my outline symbol. The outline symbol was unnecessarily complex. I downloaded the symbol years ago and assumed the 7 different layers/offsets were necessary to achieve the tint band. I assumed incorrectly and an ESRI analyst provided a 2-layer symbol that looks identical, but does not cause ArcMap to go crazy with the lines and crash.

a. Top layer is a black line:
Type: Simple Line Symbol; Style: Solid, Width: 1 pt; no offset

b. Bottom layer is a green line:
Type: cartographic Line Symbol; Width: 5 pts; Offset -2 pts (optional: Line Caps: round, and Line Joins: Round, to get rid of the jagged looking angles)
