Is anybody still using mailspring? I remember trying it back in '16 or '17 or so, liked it, but didn’t really feel the need for a standalone client at the time.
Now I’m looking forward to creating more email addresses, and multiple tabs of webmail are getting gradually less appealing. Sure, Thunderbird works…
I still run a fairly old dell laptop with 4k screen, and fedora 41.
My experience is that i needed to set dpi, scaling, and font sizes separately for kde and gnome apps, Firefox is a story in itself, and one app that I quickly stopped using - partly because I could never get it to listen to dpi settings no matter what I did - well, I recently learned that it could be used on a 4k monitor if one first were to set the right environmental variable. Tough luck, I already went with a replacement app.
Right now I only have one app that needs further custom tweaking to be legible, but since that’s only running in the background anyway, I haven’t bothered. So in short, for most apps it’s possible to configure them, but it is a pain point.
Will not buy another 4k laptop.
