Updated just now my stone old Solus and got a bad surprise again.
Both Opera and Vivaldi browsers are unusable. With Opera at least the UI is visible, with Vivaldi none. Apps itself are working fine, but rendering of any content isn't. Some icons are displayed, and even that is laggy and randomly disturbed.

Any help is appreciated...

    Then re-open them and they should be fine. This is a known issue with Chromium upgrade where it doesn't regenerate the GPUCache if there are errors with using it.

Okay, Opera could be started from CLI with parameter --disable-gpu , then t

Edit: Same with Vivaldi.
But that seems to increase the CPU load significantly.

So, if someone knows what has been broken....

    ReillyBrogan Thanks, that worked. 👍️
    Saw these files before and had the feeling I should delete them, but was afraid.
