Hello again.

After restarting my laptop, today my Thunderbird suddenly starts in a really tiny window, scaled in the wrong sense, making everything smaller than it should be. My scaling factor is set to 125 %.

It was working fine before. Any ideas why that might be and how to fix it?

I already tried thunderbird-wayland but it doesn’t change anything.

Thx!

So, I found this bug which mentions a solution:

I entered the advanced config about:config, and reset the value layout.css.devPixelsPerPx to its default. I restarted (which I’m not sure is necessary), and it worked.
