Atkinson Hyperlegible font causes lineheight issues in Dolphin file labels

Hi,

When I set the system font to Atkinson Hyperlegible like in the screenshot (the same goes for Inclusive Sans), there are line-height issues in file labels both in Dolphin proper and on the desktop, apparently any time there’s a dash in a filename:

Height of filename labels varies wildly in /usr/share

I downloaded Atkinson from https:–brailleinstitute.org-freefont and Inclusive from https:–github.com-LivKing-Inclusive-Sans, i.e. directly from the developers (it looks like I can’t post links yet). I’m running Plasma 6.1.3 and Qt 6.7.2 on Fedora 40 in Wayland.

I’m not sure if this is a Dolphin/Plasma/Qt bug or whether it’s due to the font, so before I’m filing a bug report in a more appropriate place, I thought I’d ask here. The issue I’m having may be related to https:–discuss.kde.org-t-whats-wrong-with-fonts-in-dolphin-16341.

Seems like worth of bug report, but it might be a bug with the font, too.

Did you use TTF or OTF font when installing? Also, does this font have same problems: GitHub - edent/Extended-Hyperlegible: An updated version of the Atkinson Hyperlegible font from https://brailleinstitute.org/freefont It’s apparently the same font, just more up-to-date.

I can confirm this issue:

Notice how the lines for three of the Homestuck albums and Lenna’s Inception are all lower than the other files.

It’s a very odd, it only happens in certain cases and I can’t discern the pattern here.

For Atkinson, I tried with the OTF font, and for Inclusive with the TTF font. I get the same issue with Extended Hyperlegible (OTF), also when I set the font size to 10 pt.

Sorry if this is irrelevant, but, does adding QT_SCALE_FACTOR_ROUNDING_POLICY=RoundPreferFloor to your environment variables change this at all?

No, that doesn’t seem to be the cause:

nano showing edited .bash_profile with environment variable QT_SCALE_FACTOR_ROUNDING_POLICY set to RoundPreferFloor, Dolphin with list of files with jumbled labels (base lines manually drawn in), and bash showing that the variable setting is active

You may have to set that in your /etc/environment and restart PC.

And you can double-check if something from /etc/environment or ~/.config/environment.d/<name>.conf is loaded using systemctl --user show-environment

Nope, the problem persists even so.

$ cat ~/.config/environment.d/envvars.conf 
QT_SCALE_FACTOR_ROUNDING_POLICY=RoundPreferFloor

$ systemctl --user show-environment | grep QT
QT_SCALE_FACTOR_ROUNDING_POLICY=RoundPreferFloor
QT_AUTO_SCREEN_SCALE_FACTOR=0
QT_WAYLAND_RECONNECT=1
