Thanks for that. It seems you are reporting multiple different issues here. The black flickering on window resizing seems to be a new problem so I'll make that the main bug.
The asymmetric artifacts seen when restoring from maximized is an old bug (https://gitlab.gnome.org/GNOME/mutter/issues/636) so should be reported separately. ** Bug watch added: gitlab.gnome.org/GNOME/mutter/issues #636 https://gitlab.gnome.org/GNOME/mutter/issues/636 ** Summary changed: - [regression] Artifacts appears when windows are maximizing or minimizing (Intel Apollo Lake) + [regression] Windows flicker to black when resizing (Intel Apollo Lake) -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to mesa in Ubuntu. https://bugs.launchpad.net/bugs/1835521 Title: [regression] Windows flicker to black when resizing (Intel Apollo Lake) Status in gnome-shell package in Ubuntu: New Status in mesa package in Ubuntu: New Status in mutter package in Ubuntu: New Bug description: I see the black zones, small windows breaks.
