PCB editor keeps snapping slightly off my mouse position

Hello,

I’m designing a PCB with KiCad 9.0.4 (Windows 11 x64) and the cursor keeps snapping slightly off. Every few times I want to draw something and click on the intended start point, the mouse is moved to a nearby object. Now I’m drawing the board outline and it even snaps to the existing nearby edge cut line. No traces close.

Actually, not even the mouse is moved. The object is just added somewhere else. I clicked at one raster point and it actually is located at the next point. Very annoying. I only see that the position is wrong when I continue drawing the line or shape. Then I need to cancel and try again. Most of the times, it’s still wrong. I need to change tools, move the mouse somewhere completely far away and try again. Sometimes it works then.

Also, there appear pink lines related to the wrong position. Do they mean anything?

How can I stop that? I don’t want to snap there. Snapping is usually good (I think, never really paid attention to it in a PCB editor), but this is too much.

This Forum thread is about your issue.
You may try the temporary fix I mentioned. It may work for you.
The issue has been fixed for 9.0.5 and may be available now as the 9.0.5 Testing build. See downloads in https://www.kicad.org

I don’t fully understand the other thread. I’m not doing anything off-grid. It’s the wrong grid point that’s snapped to. I very much click on one grid point and it appears my shape is drawn there, but in fact it’s added to an adjacent grid point where another shape happens to end. I’ll try to make a video of it.

There have been a few bugs fixed, affecting both selection and grid snapping. Try “Testing” it may well fix your issue and if it doesn’t raise a new issue report

Yes, they probably mean “something”. If they had no meaning, it would be a bug in KiCad.
