Flickering triangles
When the camera is at certain angles I sometimes see a flickering triangle. The game UI disappears while the triangle is visible. It flickers even when the camera is completely still as long as the angle is correct. The triangle appears to only be visible for one or two frames at a time. It alternates about 50-50 on and off but at inconsistent intervals. RTX 3060, Ryzen™ 5 5600X, on Ubuntu 24.04 using proton hotfix
