Now watching videos sucks, because of the tearing. Simply put: the browser is unusable for me. Like comment #12 said: It seems the gpu flag was deliberately disabled by the ubuntu maintainer, a step that renders the browser unusable for me. Everything worked fine without crashes before for me. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to chromium-browser in Ubuntu. https://bugs.launchpad.net/bugs/1463598 Title: Chromium 43 fails to use hardware acceleration Status in chromium-browser package in Ubuntu: Confirmed Bug description: After installing package chromium-browser 43.0.2357.81-0ubuntu0.14.04.1.1089 hardware acceleration becomes disabled.
