If you find the flashing is especially worse on Nvidia then that might relate to bug 1869750 so it will also be interesting to see if the update to 3.36.1 makes a difference.
** Package changed: linux (Ubuntu) => gnome-shell (Ubuntu) ** Package changed: nvidia-graphics-drivers-435 (Ubuntu) => mutter (Ubuntu) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1869549 Title: [nvidia] Whenever a sound needs to be played the screen blanks out Status in gnome-shell package in Ubuntu: Incomplete Status in mutter package in Ubuntu: Incomplete Bug description: Whenever a sound needs to be played the screen blanks out for a second, then the screen comes back on, and the sound plays. Examples of sounds are when I press Tab on the terminal, and there are no possible completions, or when I press the down button on the terminal, and there are no further lines below, then it blanks out, comes back, and then plays the "ding" tone telling me there are no further completions or lines. However, after one blank-out, if I keep pressing the down button, the sounds play normally without blanking out for a short time. After that period, it repeats again on doing something that would cause the sound to be played again.
