Show grid is enable but no show the grid
When I open the settings interface, the grid appears, but when I exit the settings, the grid disappears.
Alternatively, when I long press the left mouse button to spam grids, the grids only appear inside the boxes.
Also, when another program overlaps it, the grid lines only show along the edges.
What browser are you using? Also what version of Node-RED?
Can you also check the browser's dev console to see if there are any errors shown there?
browser is chrome, but I already try use edge, still have same problem
node-red version is 4.0.8
the browser's dev console no have errors
In the images you shared, the grid DOES appear though?
Do you have a Node-RED theme installed? Or have you zoomed the interface out?
What settings do you have?
Oh, I just changed the device to look at my screenshots and found that the grid exists. When I clicked on the picture on the computer, there was no grid. I think it must be a problem with my computer's display. Thank you
