Haven't checked but...

Many Macs are not able to draw a regular gl line with a width greater than 1. And I think some of those lines are a mixture of single and double-width. Fairly recently Clement added support for a line shader that does AA and supports any width line, including on Mac. I think I remember a commit where those lines changed to the new method.

So it could very well be that the complainant is seeing a difference between an old and new version that is behavior that everyone else has always seen.

VSE uses UI_view2d_constant_grid_draw to draw a grid which is shared across editors. The function has not been changed for a long time. So please check if this happens in other editors like timeline/dopesheet or graph editor.

Also check if line thickness reflects change in User Preferences > Interface > Line Width.

Wasn't this done in 2.83? or perhaps 2.90? Also this would not explain green color.

This is in 2.91, it does not happen in 2.83 or 2.90

So I opened all the editors and have discovered that if you change the size of the VSE Sequencer the lines change colour and they are nor present in any of the other editors.

There is a certain (small) height where the VSE Sequencer does not have the lines. See attached video.

Also Line width set to auto (I have factory reset)

Fiddling with line width does lead to it changing, in particular thin seems to eradicate it

Thanks, I re-checked and I must correct myself - UI_view2d_constant_grid_draw is only used by VSE

Wish I could recreate the issue - not seeing it on Windows here. But I can't see anything obviously weird in that UI_view2d_constant_grid_draw().

I've just had another run though changing Line Width between Auto, Thin and Thick
2.83.5 no extra green lines in VSE
2.90.1 no extra green lines in VSE

2.91.0-baa24f1c91d2 - extra green lines in VSE when using Auto and Thick (not visible with Thin)
2.92 Alpha (built from source) - extra green lines in VSE when using Auto and Thick (not visible with Thin)

If I set the Resolution Scale to 3 and the line width to Thick..

You can see the lines are separate to the vertical grey lines in the Sequencer, sometimes there is a single line and sometimes its a double line.

I am also confused by this since it is NOT happening on any build prior to 2.91. I am kind of hoping now the beta is out there may be more Mac users seeing it :(

Even not being able to reproduce, I am confirming the bug since the same problem has been reported again.

I ran into the same issue as @AnadinX in the VSE with the green lines in the 2.91.0 beta. I can confirm that changing Interface>Line Width from 'Auto' to 'Thin' makes the green lines go away.

It's also present in the latest daily build (2.92.0 alpha), although the 'Auto' Line Width is now called 'Default'.

@fclem since it's 2.91.0, I think it's a high priority.

I found that the issue has a rather complex dependence on Resolution Scale (as previously hinted), but also on the window size and is present for both 'Thick' and 'Thin' Line Width.
