  • Hi @helciomacedo,

    Firstly, you may try to clean your profile, as this fixes similar issue here, or simply run the Opera with fresh profile, to test if this avoid the freeze: /usr/bin/opera --user-data-dir=/home/yourusername/opera-fresh.

    If the above doesn't help, run the Opera with the switch as follows: /usr/bin/opera --disable-gpu, and see if this helps.

    Alternatively, though not so recommended (mainly for security reasons), you can try to launch it with another switch: /usr/bin/opera --disable-gpu-sandbox.

    You can also try to launch the Opera with this switch: /usr/bin/opera --use-angle=default, which will attempt to use several ANGLE renderers, until one successfully initializes. However, since the Opera already freezes, it most probably already tried all modes, and this will rather don't help.
