don't understand, please take a GIF to show the issue

Since this is a problem with dynamic placement, it would help if you posted an animated gif video or even just some screenshots to illustrate this issue rather than just a text description.

i am trying my best to work out when / why it does it, but it is a very bad bug that is hard to pinpoint. you are working away and all of a sudden the snap to grid starts failing to snap to anything already on the canvas. when you zoom out to see the entire canvas has shifted about 3/4 of the size of your workpeace. notice the Via i have circled in green bottom left, that via should be on the grid centre cross hear but the entire circuit has shifted by some amount that no longer relates to the grid snap. 

it is normal behaviour, not a bug, when you zoom the canvas, the grid line will re-build, otherwise the canvas will has a lot grid lines

@jthompson8, "notice the Via i have circled in green bottom left, that via should be on the grid centre cross hear but the entire circuit has shifted by some amount that no longer relates to the grid snap." A before and after screenshot would help to clarify the behaviour that you are attempting to describe. Like this: Here's a Cursor Origin, a section of the board outline and a via all snapped to a 0.5mm grid with a 0.5mm snap resolution:  Now zoom out:  and a close-up of the zoomed out area then shows that the grid has rescaled giving the appearance that the board outline and the via centre have moved off-grid:  I think that @UserSupport is correct in their response. <br> <br>

Sory: "Here's a Cursor Origin..." should say: "Here's a Canvas Origin..."

Sorry: "Sory" should say: "Sorry" :)

@andyfierman how am is supposed to take a screenshot before it happens when it just randomly happens as and when it feels like it?

@jthompson8, Are you saying that it is nothing to do with your grid settings and view zooming? It seems to happen often enough that you find it irritating so perhaps you could spend a little time playing with the PCB layout and taking screenshots until you either catch it in the act or find a sequence of operations that can reproduce the behaviour. Maybe use something like SimpleScreenRecorder or Peek to capture a video.

@andyfierman and talking of rubbish programing, why do i not get notifications when you reply to this tread?

@andyfierman oops wrong thread again since i can never get back to the correct page on this disorganized crappy forum. but then i guess the same question still aplies @andyfierman and talking of rubbish programing, why do i not get notifications when you reply to this any thread? if i don't look at each thread individually, i have no way of knowing if anyone has posted a reply, this forum is as badly programed as the so called Easy application it relates to.

@andyfierman quote "It seems to happen often enough that you find it irritating" understatement of the century, this is the worst bug i have seen, it is more than irritating, at best every 15 minuets it completely destroys any work you have done so far by moving everything out of sink with the grid with no means to put it back since your Undo Redo functionality fails to remember were the tracks were suposed to go if you dear to press undo it makes everything even worse than out of line.

@andyfierman right i currently have a project open in memory at the point the canvas jumped off the grid if i press undo it jumps back into the correct place (as i haven't drawn any tracks since) if i then press redo it jumps back out of sink, so the Undo Redo is actually recording whatever actually went wrong pre whatever happened  post whatever happened  interestingly it has shifted the entire canvas to the center of one of the pads of an LED so that LED component is very likely what i was working on when it actually went wrong <br> <br>

@andyfierman it is now 1 hour later and it has done it again while moving a resistor a little bit further along the line into place 

What are your Grid, grid Snap and Alt Snap settings?

@andyfierman Grid 100mil Snap 5mil Alt 1mil

post a GIF to see how do you do

@jthompson8, Does this behaviour occur in just this one project or do you see it in others?

no this happens in any project usually when you are zoomed in close to one aria so you don't notice the grid move untill you zoom back out. one month on and this is still the worst bug in the entire EasyEDA application. it randomly completely destroys entire circuits as it just randomly throws everything off snap grid when your zoomed in close to one aria trying to do something to then zoom back out to find your entire design is destroyed since nothing you did lines up any more. most of the time you can press the undo button and everything is in the undo history and you can therefor salvage your work, but as there is a bug of some sort where things failed to get added to the undo history there is occasions where undo only moves back 95% of your circuit leaving a few tracks still in the wrong place (moving 95% of the circuit back and leaving peace behind (usually tacks) is equally useless as that also destroys your circuit) im reasonably confident in saying that it is related to this drag drop bug that randomly drops the mouse selection [https://easyeda.com/forum/topic/Bug-in-Drag-Drop-3ca6174053f647589b40819627f18e0b](https://easyeda.com/forum/topic/Bug-in-Drag-Drop-3ca6174053f647589b40819627f18e0b)<br> <br>
