System Information
Windows 7, nvidia quadro 1000m

Blender Version
Broken: 2.77 RC2 1e1118e
Worked: (haven't seen it before 2.77 RC2 but I'm not sure when the last time I would have noticed it would be)

Short description of error
the dashes of the dotted line of the preview bounding box (ctrl-b box) move during sculpting mesh with multiresolution modifier

Exact steps for others to reproduce the error

open the blend file dancing bounding box lines.blend
enter sculpt mode on the selected multires modifier subdivided cube
sculpt and observe the bounding box lines wiggle near the area that's being sculpted

notes: This only seems to happen on meshes with multiresolution modifier. I know this is a silly bug to report so feel free to disregard, but I figured I'd file it because I don't remember this behavior previously. It doesn't seem like a big deal and it hasn't seemed to affect anything else that I've noticed, but in case fixing this happens to fix other things I thought it was worth reporting. It's kind of funny to watch them dance around so might be able to be considered a feature for 2.77 IMHO. EG: "New dancing bounding box lines to keep you happier while you're sculpting"

Thanks all!

Should be fun to troubleshoot this one :)

Working fine on GTX260, can reproduce on my laptop using intel integrated graphics (both running Linux). I've seen similar glitches with setlinestyle on other machines before though.

OpenGL gives no control of exact stipple pattern offset,
I've noticed different drivers behave differently when redrawing the stipple (where some jitter).

This isn't something we can fix without implementing our own stipple drawing functions, and is rather harmless too.

closing.
