I have recently updated (doing a "partial upgrade") when prompted on my Ubuntu 18.04.4 LTS and now in all browsers when I access anything, even just do a search, there is a delay of many seconds (mostly 20-30). It's driving my mad!

It's not DNS related, since I can use ping or dig and get immediate responses. The delayed behaviour is in firefox, chrome, brave and gab browsers. So it's something in the network stack I assume, but I don't even know where to begin.

/var/log/syslog shows nothing that seems to be causing this.

A problem I noticed in syslog:

Feb 20 13:07:56 roland-zenbook org.gnome.Shell.desktop[5218]: [6130:6134:0220/130756.669614:ERROR:ssl_client_socket_impl.cc(941)] handshake failed; returned -1, SSL error code 1, net_error -200

After disabling ipv6, the error is not in the log any more, but the response is still not as normal.

Any suggestions, hunches or magics I could try? :-)

EDIT: I have since upgrade my kernel to 5.3.0-40 and re-installed the Nvidia proprietary driver version 435. I'm currently running the Intel mode on my laptop, since the Nvidia mode freezes just after the grub2 boot menu.

I also installed Lubuntu/LXDE and it makes no difference, so the graphical environment I choose is not causing this.

I have now retested the browser and Firefox does not have the lag any more. The Chrome-based browsers however do. (Chromium, Chrome and Brave). I have disabled hardware acceleration in their configs, but it makes no difference.
