The problem appears to be back (see https://github.com/ubuntu/snapcraft- desktop-helpers/issues/150#issuecomment-418458767). Re-opening.
It is not observed in the snap built from source (--channel=candidate /from-source). An obvious difference is that the snap built from source connects to the gtk-common-themes interfaces (gtk-3-themes, icon-themes, sound-themes). ** Bug watch added: github.com/ubuntu/snapcraft-desktop-helpers/issues #150 https://github.com/ubuntu/snapcraft-desktop-helpers/issues/150 ** Changed in: chromium-browser (Ubuntu) Status: Fix Released => Triaged -- 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/1755119 Title: [snap] GTK dialogs have black corners Status in chromium-browser package in Ubuntu: Triaged Bug description: (initially reported on the forum: https://forum.snapcraft.io/t/call- for-testing-chromium-65-0-3325-146/4390/10) Observed on version 65.0.3325.146 from the candidate channel. This appears to be specific to the chromium snap, other snaps like libreoffice or gedit don't exhibit this. The corners of GTK dialogs (such as the one to save a page to HTML) are black instead of being transparent, and dialogs don't have shadows. See attached screenshot.
