Hi,

since Opera beta 63.0.3368.29, it looks like the ad blocker became "too effective". It started blocking also resources on localhost preventing me from using Opera for my Web development tasks, unless I add an exception to the integrated ad-blocker to whitelist "localhost".

Issue persists with: 63.0.3368.33.

Error: net::ERR_BLOCKED_BY_ADBLOCKER

I'm on Opera 60.0.3255.60 / Windows 10 (Dark theme) and I am facing the same issue. Switching to Opera "Light theme" does not help: it keeps showing autocompletion dropdowns with dark gray on dark background. My eyes are bleeding...

@ethv

@leocg said in Black/dark background (randomly) - Since Opera 72.*?:

opera://flags/#form-controls-dark-mode

Both of those settings are set to "Default (D)", i.e. they are both disabled.
This behaviour is totally random, but once that a page/site is affected, there is no way out other than restarting Opera.

I took a video, the background is supposed to be transparent, but unless it's explicitly set to a color, it sticks to black:

https://ibb.co/2s3DckZ

It seems that, at times, the browser default style for background-color:
element.style {
}

defaults to black automatically.

When it happens, opening a new tab with the same address does not help:

Every new tab uses a black background and browsing the site, still use the wrong background color. Again, CTRL+F5 is useless in this case, it looks like it's an internal rendering error. Also in this case, there isn't anything in the CSS that specified a dark background for those elements.

If Opera is closed and re-opened:

It happens in a totally random way, and I checked by:

• Enabling / disable ad-blocker -> No effect
• Verifying if there were issues in the browser console --> No errors there
• Manually modifying the CSS associated to the element using Dev tools --> It triggers the update (see below)

It seems that, from time to time, the background is partially rendered as black, even though it is supposed to be transparent:

If I manually change the CSS via Dev Tools then the page is rendered using the specified color, otherwise reloading the page (with or without CTRL+F5) has no effect at all. It looks like, at times, the transparent color is mapped to black and only changing the CSS triggers an update. Unfortunately I did not find a way to reproduce this issue in a controlled way.

Note 1: elements displayed using a black backround have no explicit CSS that defines the background color. It's just the browser default for:

element.style {
}

Note 2: theme is set to "Dark".

Hi,

pages are randomly rendered with a dark/black background, such as:

while the correct rendering would be:

Reloading the page does not help, also using CTRL+F5 does not solve the issue. The only way to get the correct rendering again is to restart Opera. That happens randomly, on different pages/sites.

Am I the only one to experience this issue?

Opera version: 72.0.3815.86

@leocg Thank you for your feedback.

I've been able to reproduce this issue with different websites, including important ones (e.g. BBC, Reuters, etc):
opera://speedtest/?url=http%3A%2F%2Fwww.bbc.co.uk
opera://speedtest/?url=http%3A%2F%2Fwww.reuters.com

Do you know if there's a way to escalate this issue to Opera Dev Team?

Thanks

There must be something wrong with opera://speedtest/?url=http%3A%2F%2Fwww.ansa.it

Can someone else confirm if this issue can be reproduced?

Thanks!

In some cases, about:speedtest runs forever.

Can someone test it with www.ansa.it? Does it work?

I am not sure if it's caused by some extension, but this is what I get in the Console:

It seems that Opera 66.0.3515.3 (or earlier?) finally solved this problem, but I can't find any references in https://blogs.opera.com/desktop/changelog-for-66/.

I reproduced this issue on 3 different systems running Windows 10 (dark theme):

Windows 10 1803
Windows 10 1903
Windows 10 1909

@l33t4opera

Issue with unreadable "autofill" persists with 65.0.3467.32. Not sure if that's the problem, it may be a regression of: DNA-77248 [Win10&Lin] Autofill is unreadable when system theme is dark (fixed in 60.0.3255.79 and re-introduced by 64.0.3417.* and later)
