I have same issue. After force close app or reboot my phone I need wait quite long to get my password on login form on every website. This happens on every new page, not only on first.

@miyukiwork I can confirm, it works perfectly! Thank you guys.

Same on my side, Opera is broken after the last update.
log:

/usr/share/libdrm/amdgpu.ids: No such file or directory
[10155:10155:1126/085414.795633:ERROR:ui/ozone/platform/wayland/host/wayland_connection.cc:197] Failed to connect to Wayland display: No such file or directory (2)

I found a solution, just start opera with the extra parameter:
opera --ozone-platform=x11

Bump. Same problem on amazon.pl. Looks like the problem seems to affect on large e-commerce sites.

By the way, I have a new notebook and a new system, and the problem still occurs

Every time I visit https://allegro.pl/ one of the opera process takes 100% of the cpu. Closing the Allegro tab does not help. I have to wait a few minutes or restart Opera
