Opera 52.0.2871.9 x64 beta loads about 20% of pages

A Former User

Opera 52.0.2871.9 x64 beta loads about 20% of pages and there's nothing I can do to fix it. Here's a list of the things I tried:
• computer restart
• clearing all browser cache and unnecessary files while the browser is closed (I have my custom batch file to do just that)
• checked latencies and made tracert to different pages and servers, mostly to those that don't load properly (no problem was found)
• restart the router several times - still no improvement

As you can see from the traceroutes the connection is quite fine:

And yet all I get from webpages (mostly from facebook) is only partial loading. When that partial loading happens, the whole page is frozen and unrefreshable, side chat is missing and the most of the post I was trying to read is missing.
