with Chromium-based browsers and with Firefox.
2. kwin_wayland uses a lot of CPU and the web page lags
3. the chat can be closed, performance restored a bit (doesn't lag anymore,
still a lot of CPU usage)
opensuse Slowroll, updated. Nvidia drivers 550, external monitor (USB C to
DisplayPort), Wayland session.
