Short update and a correction for #73 When I used gconftool-2 as noted in #74 to double checked my config for "animations" I first thought when I re-enabled animations it was not really enabled - because there was no entry under above mentioned path /apps/compizconfig-1/profiles/unity/plugins/animation. I disabled and re-enabled Animations again and even rebooted. Then I checked again with gconftool-2 for an entry at path /apps/compizconfig-1/profiles/unity/plugins/animation - but there was still none. However, I saw another white box short later, I think when I received a gmail notification in chromium, but I got a couple ones before already without white boxes. I disabled Animations in CCSM again afterwards and since then saw no white box anymore (yet, for some hours) - maybe the white boxes only stay away when I keep Animations disabled, or its just a red herring. I still have "Animations" disabled because I want to see if I get another white window over night. For the while I browsed the gconf root and found that path /apps/compizconfig-1/profiles/Default/plugins/animation is populated (see below). Is it supposed to have a "Default" profile next to the "unity" one? I seems like its the same in the screenshot from #76 (no animations under "unity" but a "Default" entry) but not in the output from #74 where its under profile "unity" - so maybe not really relevant. Tibi - have you still disabled Animations with that config and does re-enabling it show white boxes again? You wrote "before the proposed fix was applied" - did you have white boxes before or was it fine, maybe because after you re-installed the packages your "Default" profile got purged away? $ gconftool-2 -R /apps/compizconfig-1/profiles/Default/plugins/animation /apps/compizconfig-1/profiles/Default/plugins/animation/screen0: /apps/compizconfig-1/profiles/Default/plugins/animation/screen0/options: magic_lamp_wavy_max_waves = 3 magic_lamp_wavy_moving_end = true magic_lamp_wavy_amp_max = 300 close_matches = [((type=Normal | Unknown) | name=sun-awt-X11-XFramePeer | name=sun-awt-X11-XDialogPeer) & !(role=toolTipTip | role=qtooltip_label) & !(type=Normal & override_redirect=1) & !(name=gnome-screensaver) & !(name=gnome-screenshot),(type=Menu | PopupMenu | DropdownMenu | Combo | Dialog | ModalDialog | Normal),(type=Tooltip | Notification | Utility) & !(name=compiz) & !(title=notify-osd)] glide1_away_position = 1 glide1_away_angle = 0 open_random_effects = [] wave_amp_mult = 1 magic_lamp_wavy_open_start_width = 30 close_options = [,,] close_effects = [animation:Glide 2,animation:Fade,animation:None] magic_lamp_wavy_amp_min = 200 glide2_zoom_to_taskbar = true horizontal_folds_zoom_to_taskbar = true curved_fold_amp_mult = 1 dream_zoom_to_taskbar = true sidekick_zoom_from_center = 0 minimize_durations = [220] focus_durations = [150] magic_lamp_wavy_grid_res = 100 glide2_away_angle = 0 minimize_matches = [(type=Normal | Dialog | ModalDialog | Unknown)] horizontal_folds_amp_mult = 1 shade_matches = [(type=Normal | Dialog | ModalDialog | Utility | Unknown)] all_random = false time_step = 16 minimize_effects = [animation:Zoom] magic_lamp_open_start_width = 30 shade_effects = [animation:Roll Up] wave_width = 0.69999999999999996 magic_lamp_grid_res = 100 minimize_options = [] focus_matches = [(type=Normal | Dialog | ModalDialog | Utility | Unknown) & !(name=compiz)] shade_options = [] glide1_zoom_to_taskbar = false shade_durations = [300] dodge_mode = 1 rollup_fixed_interior = false focus_options = [] close_durations = [120,80,50] open_matches = [((type=Normal | Unknown) | name=sun-awt-X11-XFramePeer | name=sun-awt-X11-XDialogPeer) & !(role=toolTipTip | role=qtooltip_label) & !(type=Normal & override_redirect=1) & !(name=gnome-screensaver),(type=Menu | PopupMenu | DropdownMenu | Combo | Dialog | ModalDialog | Normal),(type=Tooltip | Notification | Utility) & !(name=compiz) & !(title=notify-osd)] close_random_effects = [] open_durations = [120,80,80] shade_random_effects = [] minimize_random_effects = [] open_options = [,,] open_effects = [animation:Glide 2,animation:None,animation:Fade] dodge_gap_ratio = 0.5 focus_effects = [animation:Fade] curved_fold_zoom_to_taskbar = true magic_lamp_moving_end = true glide2_away_position = -0.10000000000000001 sidekick_springiness = 0 sidekick_num_rotations = 0.5 zoom_springiness = 0.080000000000000002 horizontal_folds_num_folds = 3 zoom_from_center = 0
