OpenGL move not aligned to grid shown

[Tobias Müller]

When I align an object (e.g. resistor) to a grid in default canvas and switch to OpenGL the middle of the object (blue cross) is perfectly aligned onto the grid shown. However as soon as I move the object it snaps to a grid seems to be offset, however the displayed grid does not change.

So if I switch between default and OpenGL mode some of my components are aligned properly (those which only have been edited in default canvas mode) and some components are offset (those which have been edited in OpenGL mode).

Which kicad version?

I can't really confirm this on 5732, or maybe I don't understand what the issue is. Please also make a couple of screenshots that illustrate the issue.

Hi Tobias,

Could you shoot a movie demonstrating the issue?

Best,
Tom

This is BZR 5746 running on OS X from the nightly builds.

While trying to reproduce the problem in a simple file for the demo video, I noticed that it only appears if the grid origin is NOT set to 0,0. Have a look at http://misc.twam.info/images/kicad/grid_align.mp4 which shows in the first have the expect behaviour with grid origin set to 0,0 and in the second half the erroneous behaviour with grid origin set to 100,100.

Hmmm, so it appears that high values for the grid origin (1000,1000) don't have this issue. Very odd.

I can also see this issue with an offset of 1mm. It also shows only in directions with offset, so if I set (0,1) as an offset I only see it in y direction.

Seems to work with BZR 5852 for me now. Thanks a lot!
