Drawing seriesWebGlLine for big values doesn't draw correctly, seriesCanvasLine is fine

[KeeTraxx]

I'm trying to draw a fc.seriesWebglLine(), my data has somewhat big values in it (167'085'207'000), since they're unix timestamps.

I noticed that the WebGL renderer somehow doesn't render the line correctly.

I tried to reproduce this in a CodePen where I draw the same line using seriesCanvasLine and seriesWebGlLine:

The WebGL renderer just draws a straight line, also it seems to "snap" to some grid when you pan the chart up/down.

For much smaller numbers it doesn't happen (you can edit this offset in the CodePen).

That's known behaviour due to precision issues with float 32 values. See #1563
