  • Recently I installed Opera Developer 41.0.2329.0 and I found a problem, that is a big issue for me. Whenever I try to change video to fullscreen (youtube or any other site I tried, even movies saved on my computer) it takes very long time. At first, screen is black (sound still plays) and when it finally goes on, missed frames are played at increased speed and then it goes normally. Tried installing flash player, reinstalling Opera, but none of those helped. This problem doesn't exist on Firefox and Edge.

    My specs:
    Intel Core i7-6700 3.40GHz
    8 GB RAM
    Windows 10 64-bit
    NVIDIA GeForce GTX 960

  • Thanks for the report. It can be related to a display issue we already know of, but to be sure - can you please disable the hardware acceleration and see if it improved things for you?

    You can disable the hardware acceleration by going to Settings > Browser, then please scroll down, enable "Advanced options" and after that, disable the hardware acceleration under the "System" section that just appeared above.
