Opera developer builds 56.0.3010.0 and 56.0.3013.0 are crashing a lot on Linux [Mint 19/x64] as well as on Windows [Win10/x64]. Can anyone confirm?

Best reproducible zooming a lot (mouse wheel) in Google Maps, but also scrolling in Google Image search results.

Under Linux there is a SEGFAULT reported (”… in opera-developer[18f1000+58ba000]“)

You might think searching for tabs may be ”the thing“ – I understand that idea.

But it actually isn't, because the tabs – even hundreds of them – don't change position much and the human ”spatial/location memory“ is quite well developed. So it only happens ever so seldom that you search for an open tab and don't find it hovering in instances.

On the other hand, it happens a lot more often that you accidentally close a tab and want to re-open ist quickly; not using keyboard shortcuts the ”Tab Menu“ comes handy there – much more convenient than unintuitively being redirected via the (sometimes painstakingly slow) history panel.

[opera://flags/#search-in-open-tabs came handy for me, there, for the time being]

Yet another shareholder focused decision that discounts significant parts of your core community.

DNA-86730 Extend chrome.tabs API to allow opening URLs in selected workspace

@ralf-brinkmann Your last point seems to be related to / reflect what I described below.

DNA-90087 Allow for native installation of Chrome extensions

So it won't be worth it anymore to maintain ones extensions in Opera's addon store?

Am I right to assume, that it will be sunset soon? I mean, I take it as a hint, that one of my extensions still is awaiting moderator's approval since August… Duh.

Just like some builds a few month ago, this build again starts up with fulfilling media query @media (prefers-color-scheme: dark) {…} despite having the light theme active (toggling →dark theme → light theme is a workaround for the session).

It seems like Opera's history search feature throws sporadically, when entering stuff into the address field (aka omnibar):
Uncaught (in promise) →Object chrome://op-resources/modules/services/history.js:19

The result is a non-responsiveness to [Enter] of the tab.

[Opera/dev/latest, Win10/latest; chrome.omnibox extensions active]

As you say there is no configuration option to select the language version built-in Wikipedia search uses.

As @leocg suspects, Opera probably uses system locale to determine the Wikipedia language version: Neither Opera UI-language nor language preferences (→ Accept-Language: .. HTTP header) influence the Wiki search language, experiments prove.

I can suggest my Xeno Wikipedia (addons.opera, chrome web store, …) extension, though, which allows you to set an arbitrary default while being flexible to allow you to request other language versions occasionally. Maybe it suits your needs.

@rseiler said:

You are right. That's a prototypically bad wording guaranteeing user confusion.

Opera 73.0.3834.0 crashes instantaneously clicking "YouToube Music" button in the new sidebar player.

@olesiak Using last developer build or the current one [71.0.3763.0] on both, Linux [Mint 20, Cinnamin, 64bit] and Windows 10 [latest, 64bit] snapshot tool does not work reliably. You may try on Google Maps, where it just copies white. Or OpeenStreetmap.org, where it copys seemingly nothing. Or Planefinder, ... Maybe it's canvas related.

The very handy snapshot tool isn't working reliably anymore. Snap shoots black or wrong layers (z-index wise).

For the last couple of developer builds choosing O » Exit (the ”Exit“ option from the ”O“-menu) does not exit Opera, but shows the hint ”Hold Ctrl-Q (or press twice) to quit Opera“ in a window centered, semi transparent overlay bubble. Only on Linux, that is (Linux Mint 19.3 / Cinnamon).

This is supposed to happen only when pressing Ctrl-Q once (to prevent closing Opera accidentally, e.g. when the intention was to close a tab with Ctrl-W) – not when exiting via the menu.
