I was getting a very slow start and these messages appeared when using the command line:
[9977:9977:1003/140651.502921:ERROR:sandbox_linux.cc(369)] InitializeSandbox() called with multiple threads in process gpu-process.

Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.

After a little hustle, I discovered that using the --password-store=basic makes Opera much faster again. I tried also with --disable-gpu --disable-software-rasterizer --password-store=basic --no-sandbox. However:
- Sync appears to be broken (every time I open Opera, It says that it's unsynced)
- Microphone does not work (e.g. on WhatsApp web)
- Last but no least, when I close Opera, few processes still active, and if I want to open Opera whith these, I have to wait a lot until it opens.
I have tried with a clean instalation a 100 times and It solver nothing. Thanks in advanced.
