Hello, Upgrading to the latest chromium seems to have fixed the problem of the window being displayed as a white box without any controls.
Upgrade: chromium-sandbox:amd64 (97.0.4692.71-0.1~deb11u1, 97.0.4692.99-1~deb11u2), chromium:amd64 (97.0.4692.71-0.1~deb11u1, 97.0.4692.99-1~deb11u2), chromium-common:amd64 (97.0.4692.71-0.1~deb11u1, 97.0.4692.99-1~deb11u2) Note that I am still getting plenty of error messages on stdout/stderr when invoking chromium --temp-profile from the command line. See below. You may want to close this bug. I would be happy to file a separate bug report(s) for any of the error messages below, however you would advise. ---------------- $ chromium --temp-profile Using temporary profile: /tmp/tmp.60BqxExgbm libGL error: failed to authenticate magic 1 libGL error: failed to load driver: radeonsi [32220:32307:0123/132117.954017:ERROR:chrome_browser_main_extra_parts_metrics.cc(227)] START: ReportBluetoothAvailability().
