This site corrupts Opera's rendering engine in every tab

  • This really shocked me. I opened this site, tried to listen to the radio, it didn't work, and then all other tabs started to have strange black or white rectangles and were completely unusable. Closed, reopened, tried again and the same issue occurred!

    Then I tried with the latest version in a portable installation and it still happened there. What can be happening?

    This is the site:

    You may have to switch tabs a few times until this problem starts. Beware that you will have to close your browser afterwards!

    This is how may look after visiting this site:

    I couldn't reproduce this issue in either Chrome or Vivaldi.

  • Radio doesn't work here too but i don't see any rendering issue.

  • Here's an example of how it behaves here:

    You may need a few more clicks, scrolls or tab switches and that's all.

  • Probably region-blocked (only accessible in Argentina) ... just an MP3 stream though.

  • You may need a few more clicks, scrolls or tab switches and that's all.

    I still don't see any rendering issues.

    What is your version of Opera, OS and graphic card?

  • The mp3 stream doesn't matter is in this case, I don't even have to press Play for this to happen.

    This happens with Opera 38.0.2220.41 and 41.0.2353.56 on two different computers, both with Windows 7 Ultimate x64 SP1. One is a notebook with onboard Intel graphics and the other a desktop with NVIDIA graphics. This happens in the notebook also via Remote Desktop.

    If I disable hardware acceleration, this doesn't happen.

    I tried with a remote computer in California with Windows 7 Professional x64 SP1, Opera version 41.0.2353.56 and AMD Radeon graphics, and I couldn't make it happen, although maybe it's because it's not using hardware acceleration despite being enabled. Is there a way to confirm if it's actually being able to use that?

  • If I disable hardware acceleration, this doesn't happen

    So you've found the cause. 🙂

    Probably some issue with Nvidia drivers. Have you checked opera://gpu/ for some info?

  • i cant even open the website ...

  • Confirmed remote desktop to the PC in California doesn't use HW acceleration.

    Well, I have never had an issue with my graphics card, it's a GTX650Ti with updated drivers. I don't visit that site frequently, actually just came across it and was shocked when those black rectangles started popping up.

    I thought it would be some issue with Opera, as other browsers survived the frantic tab switching. If nobody else could reproduce this, I guess you can forget all this. :party:
