I have Macbook Pro with 2 video cards: One is Intel HD3000 and another is discrete AMD Radeon HD 6750M.
Problem with online video. As I understood support for Intel 3000 chipset disabled. Opera works in software mode (I mean no hardware acceleration). But it cannot open video almost everywhere.
If I turn on discrete GPU manually and restart Opera - hardware acceleration turns on. And I can watch online video.
- Please fix HD3000. Cause Firefox and Safari work with it without any problem.
- Opera has to check on how many and what kind of video cards are in system. And switch between it in auto mode or, at least, ask a user for switching. Some native Mac apps (such as Apple Photo for example) turns on discrete GPU instead of build-in when they are started.
Macbook Pro, Latest macOS Sierra. Opera for mac 40.0.2308.81.
