Description david gowers 2007-03-24 01:12:35 UTC 
Steps to reproduce:
 1. Create a new image, fill it with white
 2. Bring up the grid configuration dialog.
    Set the grid to 1x1 or 2x2, and the drawing style to solid.
 3. Make the grid visible.
 4. Zoom in until the vertical lines disappear. I've found this happens at
    9000%, 18000%, 25600%; It doesn't seem to matter what spacing the grid is set to. The vertical lines show up at all other zoom levels.

*** This bug has been marked as a duplicate of 76096 ***
Comment 2 david gowers 2007-03-24 10:54:38 UTC 
.. What? It has no obvious resemblance. Surely the grid is not subject to the same kind of nearest-neighbour interpolation as the image.
comment #17 to bug 76096 refers to the Grid filter, which renders pixels onto the image. This bug refers to the image grid, which is independent of the image content and is never rendered on to the image, only above it.

And the image grid never disappears when zooming out (checked from 100% to minimum zoom with 1x1 and 2x2 grid), which is the primary issue addressed by that bug report.

I'm reopening this on the understanding that you misunderstood it.
Comment 3 Michael Schumacher 2007-03-24 11:18:49 UTC 
You should specify the GIMP version, though.
Comment 4 Michael Schumacher 2007-03-24 14:53:16 UTC 
I can't reproduce this with current CVS.
Comment 5 Sven Neumann 2007-05-07 13:21:57 UTC 
I can reproduce this (using SVN as of today). Sometimes both horizontal and vertical grid lines dissapear. Exposing parts of the image window brings them back, but often at the wrong position.
Comment 6 Michael Natterer 2012-01-08 22:01:30 UTC 
Please try GIMP 2.7.4 and report back.
Comment 7 Akhil Laddha 2012-02-21 12:44:53 UTC 
Could you please try to reproduce problem with GIMP 2.7.4 or later version and update the bug report with your finding, tia.
Comment 8 Alexis Wilhelm 2012-03-24 17:50:28 UTC 
As expected, this bug got fixed with commit 529ce40a5d92d9c9957c7e8350ce48ffbcad033a.
