Background grid in BP editor is more prominent/visible than expected (thicker lines)

Development Programming & Scripting Blueprint

I recently noticed a change in how my grid looks inside the editor (the background grid when opening a Blueprint for example).
The background grid is much more noticeable (thicker lines). See image below:

I find it quite distracting… I’m using Unreal Engine 5.3.
Has anyone experienced something similar? Are there any settings/hotkeys that I might have accidentally used to change how the background grid is displayed?

I have the same problem

Also getting the same behaviour here suddenly, even in clean projects.
Seems like it just changed recently for some reason, also seeing this both in 5.2 and 5.3
Would really love to get back the thinner not so obtrusive gridlines as well

I just updated my GPU drivers and it’s happening to me as well. If anybody figures out a fix for this, please let us know.

Edit
I rolled my GPU driver back to:
537.58-desktop-win10-win11-64bit-international-dch-whql.exe
This has fixed it. So it seems something in newer drivers is doing it.

Still looking for a solution.

I updated my GPU driver and now have the same problem.

Just updated my drivers as well, same problem, mine are very bold and ugly, hard on the eyes… wtf

I’ve opened a case for this with Nvidia. I noticed there was a corresponding post for this on the Nvidia forums with no traction.

Nvidia Case # 240311-000436 (its under my account so no public tracking that I am aware of yet).

I am sure some seeing the sight of a gridless background is like nails on a chalk board :stuck_out_tongue: to be clear, its a joke and I would never work gridless (to OCD). But you can adjust the Grid lines to your liking within the editor preferences under the ‘Graph’ category under appearance settings.

Just checking in. Does anybody know if this has been fixed? I’m still using older drivers and would like to update if possible.

Seems to be an alpha issue. The only workaround I can find is:

Open Editor Preferences:

Search Bar, copy and paste: Grid Regular Color

Change the A to something around .5

Search Bar, copy and paste Grid Ruler Color

Change the A to something around .6

Search Bar, copy and paste Grid Center Color

Change the A to something around .5

Interesting fix. I’ll have to try that sometime soon when I’m ready to update my drivers and deal with all that.

Thank you for the suggestion Jon!

Well I finally got around to trying it. Unfortunately that didn’t fix it however it helped a little. It seems to be an issue of line ‘thickness’ more than anything for me. However I don’t see anywhere to adjust the thickness of the grid lines.

If anybody figures out how to adjust this, please let the rest of us know!

Just happened to me today. It happened randomly, unprompted. I closed UE on Saturday, and it was normal. I opened it on Monday and got 2px thick lines. The only thing I can think of is that I was playing a UE5 game earlier and got a GPU crash, so that’s my best guess for what caused it. I updated my 3080 TI drivers to latest and updated UE from 5.4.3 → 5.4.4 and still have thick lines.

This is going to drive me crazy. I’ll probably just have to deal with adjusting the alpha for now.

This has been driving me crazy, so I dove into the code and found that enabling anti-aliasing on the grid lines makes things acceptable again.

If you’re building from source you can just set bAntialias to true in…

  • SNodePanel::PaintBackgroundAsLines
  • SDesignSurface::PaintBackgroundAsLines

Otherwise here’s a pull request to add a toggle for that: https://github.com/EpicGames/UnrealEngine/pull/12764
