Steps to reproduce:

Have the density of Thunderbird set to "Compact"
Store a contact with the letters q, p, g, j, or y.

Actual results:

The letters are cut in the Contacts List both in the contact name and in the e-mail address.
I think this bug was introduced with version 102.0.3. Maybe it's related to the fix of the contact picture size.

Thanks Andreas, good bug report!
Didn't see yours when I filed mine today - bug 1781114.

Yes, most likely regressed by bug 1776078.

This isn't harmful, but it's pretty bad UX as it will make addresses with such characters all but unreadable (as seen in screenshot above) -> P2.
Alex, can you make a plan?

Do you also have a larger font size?
I can't reproduce this unless I increase the font size a lot.
In the screenshot I have compact density and font size at 15px compared to the default 12px.
I think this is a mix of font sizing and font family.

From your screenshot also sizing and spacing seem different than the default. Do you have any userChrome customization or add-on changing the aspect of those items?

There's no "quick fix" for this, the only thing that can fix it is updating the core code of the treelistbox in order to set the height of each contact element based on the font-size, rather than having a fixed predefined height like we have right now.

This architectural change is scheduled for the future.

102.1.0 (64-Bit), Windows 10

I have regular font size (used reset to make sure). View > Font size > Reset font size.
No customizations, no add-ons (verified with Trouble Shoot Mode).
So from my pov, this fails for the default case.

I have some Windows display scaling applied, but that shouldn't matter as it will scale everything equally.

And indeed, as hinted by Alex, after using "Increase Fontsize" a lot (to XXL), the layout breaks completely :-/

Alex, is this a screenshot on Windows?
Why is the font white on yours?

That's on Linux, don't worry about the screenshot as that was taken when the window didn't have the focus, that's why the weird faint blue color.

So from my pov, this fails for the default case.

I see, I was able to reproduce this on macOS.
I'll see if I can find a quick fix, otherwise as I said, this will unfortunately be fixed later during this cycle.

Well, I ran mozregression and this was regressed by bug 1776078 D150214... So as the display has been correct all along before (haven't checked scaling, but the default case at least), maybe this can be rectified.

I think we can solve this by adding

ab-card-listrow .ab-card-second-line {
  line-height: 1.2em !important;
}

Thomas, can you confirm doing so fixes the issue on Windows and doesn't create any weird outcomes?

Tested on 102.1.0 (64-bit).

You also need to fix the name row which has same problem. 1.2 is not enough for me. 1.3 (without em) fixes this for me for the default size.
Font scaling still breaks the layout because of the fixed 36px height and fixed row positioning - current hard-coded implementation is so weird!

ab-card-listrow :is(.ab-card-first-line, .ab-card-second-line) {
  line-height: 1.3;
}

Micah, can you take care of this to create a patch with the changes suggested on comment 10?
Make sure the edit doesn't affect negatively the various density variations in the Address Book and it's not affecting Linux (and macOS if you can otherwise I'll test this during review).

Assigned is only for when a patch is present.

(In reply to Alessandro Castellani [:aleca] from comment #12)

Assigned is only for when a patch is present.

As discussed, in terms of bug management, we really want to preserve the literal meaning of the flag for bug searches etc. where Assigned == assigned to someone to work on it, regardless of patch presence. Which looks like the original intention and is much more helpful.

Of course everyone will be most happy if it's assigned and has a patch... so following my testing of Aleca's idea per my comment 10, let me just offer the patch - here it is! ^^ ;-)

We should try to fast-track this as much as possible because distorted characters in default AB view aren't nice at all, can actually make entries unreadable.

So per Aleca's subsequent comment, turns out that Micah was already working on this in an orphaned diff with the wrong bug number (now rectified) -> returning this to him. It's good to see action on this!
