In a document of dimensions 4096 x 1536, the dotted style grid fails to be drawn beyond 2000 pixels from the left, when viewing the document at 50% magnification or greater. Here's a screenshot:

Ah I think you misunderstood me, this is a bug report, not a support request.
I'm talking about Photoshop's internal grid overlay, you know, CTRL+H.
Edit > Preferences > Guides, Grid & Slices
The grid appears fine at < 50% magnification, or when in line mode.
Yes, completely misunderstood. Now I see what you mean. There seems to be a limit of 200 x 200 displayed points.
(When 25% <= zoom < 50%, the point-grid is being drawn at half-density, horizontally and vertically, therefore it can cover a region that's twice as wide and tall as when zoom >= 50%.)
John_Data, this forum is before all a user to user forum, you are not addressing Adobe's teams here.
If you want to report this issue (that is maybe linked to limitations in your videocard) to the Photoshop teams, I suggest that you post at http://feedback.photoshop.com that is meant to report bugs or suggest features requests.
But it is not because it is reported, and maybe acknowledged that it will be fixed immediately. It needs to be checked by QE to see if the fix does not cause other issues, etc.
If you have issues logging in, check this thread: http://feedback.photoshop.com/photoshop_family/topics/how_do_i_registe r_a_new_account_for_this_photoshop_com_forum
Hm, perhaps someone in Adobe engineering did not allow an OpenGL buffer to be large enough...
I can reproduce this, and I have a setup that supports up to a Max Texture Size of 16384 x 16384, so the OpenGL implementation itself should not be the problem.
