Display goes dark when selecting Home or "Active Apps", after changing "Display size" setting
Issue description, as found on Taiga
In Settings, Display Settings, Advanced, I changed “Display size” to Small. The display went dark when exiting Settings. Error message sometimes “Launcher3 isn’t responding” with options to Close app or Wait. Restarting fixed this, and Display size stayed “Small”. Then I changed the setting to Large, same result, the display went dark when exiting settings, and restarting fixed it. Display size stayed Large. At some point, by snoozing (“blindly” since the display was already dark) the display with power button and then wake it up again, I could get the display running again without restarting. Same behaviour when changing “Display size” back to “Default” after changing to Small or Large.
