I'm not a dev here. Hi Mazin! So the flickering only occurs for some time after the screen wakes (ie. either from hibernation, screen lock(when screen turns black) or a boot). I have seen that on battery, the flicker vanishes pretty quickly than when plugged in. Also, once stabilized, the flicker is not observed in that session till the screen turns black (lock, hibernate, boot). |
