Olivier: I am running revision 1213 on Kubuntu 20.04. Removing ~/snap/chromium/common/.cache fixed this issue for me, and it has not returned after multiple restarts nor after I installed the font as described in comment #11.
Before I removed the .cache directory, my file dialogs did look very much like the screenshot Steven posted in comment #1, with rectangles instead of letters. But now that the letters are back, I notice that many of the icons are garbled, which is different from Steven's screenshot. So for sure at least the icon part is a different issue, and I will look to see if anyone else has posted it, or else I'll post it as a new bug. I am now assuming that my font problem was a different issue as well, so I'm going to stick with the revision I have, unless it would help you for me to try revision 1221 too, in which case please let me know. :-) ** Attachment added: "Screenshot_20200709_073623.png" https://bugs.launchpad.net/ubuntu/+source/chromium-browser/+bug/1864365/+attachment/5391039/+files/Screenshot_20200709_073623.png -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to chromium-browser in Ubuntu. https://bugs.launchpad.net/bugs/1864365 Title: [snap] Dialog font missing Status in chromium-browser package in Ubuntu: In Progress Bug description: $ lsb_release -rb Description: Ubuntu 19.10 Release: 19.10 $ snap info chromium name: chromium summary: Chromium web browser, open-source version of Chrome publisher: Canonical✓ store-url: https://snapcraft.io/chromium contact: https://bugs.launchpad.net/ubuntu/+source/chromium-browser/+bugs?field.tag=snap license: unset description: | An open-source browser project that aims to build a safer, faster, and more stable way for all Internet users to experience the web. commands: - chromium.chromedriver - chromium snap-id: XKEcBqPM06H1Z7zGOdG5fbICuf8NWK5R tracking: latest/stable refresh-date: 3 days ago, at 01:56 CET channels: stable: 80.0.3987.116 2020-02-19 (1036) 160MB - candidate: 80.0.3987.116 2020-02-19 (1036) 160MB - beta: 81.0.4044.17 2020-02-17 (1028) 161MB - edge: 81.0.4044.17 2020-02-14 (1028) 161MB - installed: 80.0.3987.116 (1036) 160MB - Basic Ubuntu 19.10 installation using "factory default" font settings.
