I have downloaded the same build and installed on Windows-10 having AMD Radeon HD 8400 / R3 Series. Still I couldn't reproduce it. It seems a regression issue based on the comments. Could you please provide the regression range ? Installation and usage of mozregression too is attached (if needed). Thanks a lot. -- Version: 53.0a1 Build-ID: 20161128030212 Update-Kanal: nightly User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:53.0) Gecko/20100101 Firefox/53.0 Betriebssystem: Windows_NT 10.0 Fenster mit mehreren Prozessen: 1/1 (aktiviert (Standard))
