Is there an SDDM issue to track this? Because I edited the file to make revealPasswordButtonShown true, and the button shows up just fine. Which makes me think this might've been fixed in SDDM.

I am not sure, but I think the issue is when the breeze icon theme isn't available, then the button would be shown without an icon, i.e. invisible, and we got bug reports of users hitting hit by mistake. Given the nature of the text box we're dealing with here, hitting that invisible button by mistake is problematic security-wise.

One way to fix this is if sddm have copies of the needed password buttons, then it should work regardless of the installed icon themes.

I see. So the bug is seen only if Breeze icons aren't installed? Because I read that it happened only on some systems, but I didn't know which exactly.

Doesn't/shouldn't PC3 fall back to other icon themes if Breeze isn't installed?

we could install an icon into hicolor as fallback

Some time ago I tried finding which icon was being used, but I didn't get anywhere and moved on (I copied the theme folder, modified the file to show the password and used the custom theme ever since).
