Text Appears as Rectangles in Modal Windows (Snap Version, Ubuntu 24.04)

[Abrham-m]

Problem

On Ubuntu 24.04, when I open a modal in Super Productivity (Snap version), the text appears as rectangles.

Steps to Reproduce

1. Install Super Productivity via Snap (sudo snap install superproductivity).
2. Open the app and trigger any modal (e.g., closing window confirmation).
3. The text inside the modal is unreadable (only rectangles appear).

What I Tried

• superproductivity --disable-gpu --no-sandbox
• Installed fonts-noto-core and rebuilt font cache
• Switched GTK theme using GTK_THEME=Adwaita
• Ran glxinfo | grep "OpenGL renderer" (output: Mesa Intel(R) Xe Graphics (TGL GT2))

Environment

• OS: Ubuntu 24.04
• Super Productivity Version: (get it with snap list superproductivity)
• GPU: Intel Xe Graphics
• Display Server: (Check with echo $XDG_SESSION_TYPE → wayland or x11?)

Expected Behavior

The text should be readable.

Actual Behavior

Text appears as rectangles in modal windows.

Thank you very much for opening up this issue! I am currently a bit overwhelmed by the many requests that arrive each week, so please forgive me, if I fail to respond personally. I am still very likely to at least skim read your request and I'll probably try to fix all (real) bugs if possible and I will likely review every single PR being made (please, give me a heads up if you intent to do so) and I will try to work on popular requests (please upvote via thumbs up on the original issue) whenever possible, but trying to respond to every single issue over the last years has been kind of draining and I need to adjust my approach for this project to remain fun for me and to make any progress with actually coding new stuff. Thanks for your understanding!

I'm not sure how helpful this remark is, but I've seen similar problems with other apps distributed as Snaps in the past. The problem there was related to the sandboxing that Snaps use, which prevent the apps from accessing the needed fonts.

"rm -rf ~/.cache/fontconfig && sudo fc-cache -r" - worked for me

✅ Issue Resolved!

The problem was fixed by clearing and rebuilding the font cache. Here’s what worked for me:

rm -rf ~/.cache/fontconfig
sudo fc-cache -r
