Hello Device is Lenovo A7000 Lineage OS 15.1 (8.1) White screen covering page until I go to my login data, then it disappears, sites are rendered as is shown in tabs menu. I had this exact problem on my stock VIBEUI ROM 6.0, so Lineage OS shouldn't be an inssue. I had this problem at least 2 years. Did someone encourage with this problem ? I also have this problem in Firefox Preview Nightly and Tor browser. Thank you for your response.
