After Big Sur update, i have Big problem with horizontal lines over display and freezing parts of background.
Repeated SMC & NVRAM reset not working.
In the first phase sometimes help just close and again open display, but it doesn't help now.
Can't work now :(
(MacBook Pro 13 | 2018 | 4 Thunderbolt 3 Ports | i7 2,7 GHz | 16 GB RAM | Intel Iris Plus 655 | 22 months from purchase)
MacBook Pro 13″, macOS 11.0
Reinstalled Big Sur two times and nothing work. :(
Sometimes, when close and again open display, black lines dissapears, but screen startiing blinking. When repeat, black horizontal lines is back and backgraund start freezing again.
Screen shots are clear, without black lines and freezing.
External monitor works. Before uppdate to Big Sur, everything worked perfectly fine!
As I wrote in another post, after update to Big Sur it started to show me a warning, that I have to replace the batteries in service. 22 months old batteries! I think it will be related to the charging, therefore bad system settings in OS Big Sur (because Apple M1).
Hi OndreiOne,
same problem here, MacBook Pro 15 2019, I partially solved the problem disabling "Automatic graphics switching" form system preferences (energy control panel).
Now the computer is working fine, except right after waking up the computer, horizontal lines are back for few seconds.
Hope they solve this problem on the next update.
Same here! With my MacBook Pro 13” 2017. Always perfect, never ever had any problem. I updated to Big Sur about a week ago and yesterday morning when I turned it on, the same lines suddenly appeared. I tried every possible reset, downgraded back to Catalina too, but nothing seems to work :(
Plus, I don’t have the graphics switching option... any help?
