<![CDATA[Certain popular sites (e.g. Thomann.de) do not render correctly and/or cause "Out of Memory" errors]]>I have used Opera for years now, but a few months back certain sites started showing signs of not rendering correctly, looking like CSS is not being considered at all.

One site that consistently produces this erroneous result is Thomann.de - which is looking like this:

40899484-3c36-4dcb-99f3-14cab37f6365-image.png

Keeping this Page open will cause a "Out of Memory" error being shown. Other browsers like Chrome, Firefox or Edge work just fine. I also noticed this happening on other popular sites, like Disney+ , which renders correctly visually, but shows the same error after keeping the page open and watching videos for a while. It consistently happens only on certain sites, to a point where interaction is sometimes unresponsive or not happening at all.

To test what is causing this problem I installed Opera GX alongside my normal Opera. This test was using :

  • a clean profile
  • a blank out-of-box unsynched GX browser that I just installed today as of this post
    LVL4 (core: 91.0.4516.106)
    Update stream:Early Access
    System:Windows 10 64-bit
  • with no extensions installed
  • internal adblock disabled, trackers allowed

I get exactly the same result opening Thomann.de and I am running out of ideas on what to do now.

It's always the same sites consistently, but I cannot identify what their common denominator is.

Looks the same on Opera and Opera GX (with a blank profile and all blockers disabled)

As stated above I have "Trackers allowed". Or is there another setting that I'm missing that you refer to?

Also tried "Allow all cookies" and repeated opening the site. No change. The site is completely locked up and I cannot even get past the "Served with love" window.
