Hi pedri.uchiha,
We would advise you to back up your data and try a factory reset.
Please check your Battery mode and try setting to " Performance", and check again.
If the problem still appears, please show me a short video of the problem. This may help us look into the problem greatly.
To share videos, please upload it to ASUS WebStorage (https://www.asuswebstorage.com/navigate/) and share the link with us.
Please also tell me when opening which apps cause this problem.
Thank you 🙂
