Hello @sgf69, thank you for bringing it up. Have you try by enabling or disabling the option that says Block Scripts under shield settings? By any chance are you using any kind of extension? If so, please try disabling all of them.
Besides this, can you try disabling Hardware Acceleration in settings to see if this resolves the issue?
You’ll find this in Settings --> Additional Settings --> System --> Hardware Acceleration
Also, go to brave://flags > Search 'Vulkan' >Disable > Vulkan> Retest
I first disabled Hardware Acceleration which never changed anything (after having restarted the browser).
I then tested opening these sites which weren’t working in private mode and some are fixed, but not all unfortunately. This indicates to me it could be a caching issue. I then proceeded to clear my entire cache, restarted Brave, logged into my sites and unfortunately this issue is still occurring on Gitlab, Amazon, Netflix, my Proton Mail page, Whatsapp web…the issue actually seems to be worse now with most websites loaded, me not being able to extend the advanced shields.
I will try the Vulkan retest step you shared and feedback.
