Steps to reproduce the bug

1. Open the URL above on either Microsoft Edge or Brave(I haven't tried it out on chrome) and resize the window to half the screen's size.

What did you expect to happen?

I expected to see the chess board.

The chess board was hidden. Even after using Ctrl + Shift + R, the issue persisted.

Operating system

Windows 11

Browser and version (or alternate access method)

Brave 1.51.114,Microsoft Edge 113.0.1774.42

Additional information

The image shows how the page looks like on resize.

Brave:

Microsoft Edge:

The board shows up when I open the inspector panel.
Error observed in the console:

fused to load the stylesheet 
'data:text/css,%0A%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20ddg-runtime-checks%20%7B%0A%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20display%3A%20none%3B%0A%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%7D%0A%20%20%20%20%20%20%20%20%20%20%20%20' 
because it violates the following Content Security Policy directive:
 "style-src 'self' 'unsafe-inline' lichess1.org". 
Note that 'style-src-elem' was not explicitly set, so 'style-src' is used as a fallback.

cant reproduce, I am on Arch Linux and I have tried on Chrome and Firefox, with and without signing-in. Seems like a user specific issue from your side.
Did you try changing the window size through inspecting where people check the responsiveness?

[Zeddling]

Interesting.
I have right now. The board shows up when I check on responsiveness. When I turn that off it goes back to the same issue. Opening the inspector panel however shows the board again. I'll add the error I see on the console to the description.

I'm having a very similar issue. I'm using manjaro/palemoon. I posted a picture of the issue here. https://lichess.org/forum/lichess-feedback/resolution

I have the same issue on Windows 10. Both on Chrome and Brave, with and without login. Also in incognito mode, so it shouldn't be an extension.
Issue does not appear on Firefox.

For me, the board disappears from a width of 580 to 798 pixels. If the browser window is larger or smaller, the board reappears.
