#5641 new defect

Painting error layer is very slow

Description (last modified by skyper)

When error layer in validator is visible and being painted, scrolling through the map is very slow - with medium size map (~ 8000 ways, 32000 nodes), when I zoom in close, the scrolling is smooth, however if I turn on the error layer, the scrolling goes to about 1 redraw per 2 seconds.

I suspect that the error layer is not using quad buckets or any similar algorithm to speed things up and only draw things that are actually visible.

Although, even when zoomed out (so entire map is visible), the redraw speed is much worse (approximately 3 to 5 times slower with the error layer than without it)
