Hi, Thank you for the quick reply. I prepared my bug report this Friday but could no post it because of some issues with the access management system [0]. I just saw that some updates where available and I am on 5.4.13-1 now but had this error once already. I will try do disable adaptive screen brightness as mentioned in the Dell support link you have posted as well as with the very latest kernel build from the Kernel:stable repo.
