      Weird. I was only able to reproduce something similar by enabling the sidebar menu (as per @andrew84's comment) and clicking alternatively on Speed Dial and Extensions. Otherwise, it doesn't seem to happen. I have dark background pages in my Speed Dial, which also has a dark background, but no flashing happens.

        Its probably cause I have the win10 nightlight settings on, which makes this issue even worse.
        Ive had the sidebar disabled forever as there is nothing on there I find usefull, so its nothing to do with that.

        There must be a way to turn this to black if its indeed necessary

          The white might be the about:blank page showing before the initial display of the requested page (or just the page itself where it hasn't received styling info yet). If so, you can try to find a solution for Chrome to style the background color of about:blank and it might work in Opera too. Don't know if there's a solution though. More likely, you'd need to find a way to edit the default styles for a page and set its background-color to black for example. You might be able to do that for all pages with an extension.

          There's an old post at https://superuser.com/questions/580228/prevent-white-screen-before-loading-page-in-chromium with some workarounds that no longer work, and a reference to a bug. There might be a solution that still works somewhere in there.

            @burnout426 there's also a similar bug in Chrome bug store.
            https://bugs.chromium.org/p/chromium/issues/detail?id=853986
            If I don't mistake, there's a issue with white 'flashbangs' on all the Chromium browsers. And each browser has some own workarounds.
            Previously there were white flashbangs when creating new tabs or switching background tabs (that's why Opera implemented 'shared startpage' flag for the 'new tab', I guess). The bug was closed/fixed/reopened/merged many times with other similar bugs. I don't what happens there on chromium engine, but comparing to FireFox for example, in FireFox it works smooth and without any flashbangs (white or colorful) when creating new tabs or switching background tabs.

                    Well ive gone through the chrome and firefox work arounds, and nothing seems to remove it.
                    Its getting even more anoyying now cause im expecting it.
                    Seems the only work around Ive found is to click, then look away....... not ideal....

                        @Pebbles1980 You can check my posts in the blog too, I don't know whether they going to fix it or optimize. In the first link you also can find a link to the Opera 65 announcement where in 'after' demo video they demonstrate how do SD tiles open now. If I don't mistake, it worked like on this demo recently (not ideally, but worked ), now there is a flashbang prior to the opening bookmark all the time.

                            @Pebbles1980 It was fixed in in 65 version as it seems, I don't remember when it was spoiled again.

                              Yeah ok, It still does it in the new beta too.

                                @Pebbles1980 You can also check how does it work with background tabs (when you open bookmarks/links by clicking mouse's wheel or right click > 'open in new tab'). When you visit background tab for the first time you'll see a full screen flash also, on all chromium browsers.
                                It's engine issue, as it seems. As far as I know, Chrome (Opera and Edge too) uses a workaround for this: the background tab you are activating will use previous tab's web page background color for the flashbang effect (to exclude the all the time white flasbangs ).
                                For example, if you're now on web page with white background and open a dark page in the background tab (steam page or youtube in dark mode for example), when you active the tab you'll see a white flashbang. If you're currently on dark page (steam page for example with dark blue background), and open some white page in the background you'll see a dark blue flashbang before page appearing when you activate the background tab. If you open few dark pages in a row in the background, the flashbang's color will stay dark (dark blue for steam/dark gray for you yotube) until you visit some page that has a white background.
                                So regarding the flashbangs, all the chromium browsers are headache for me.

                                  Thanks for that Andrew. I never noticed that. Ill try to keep everything on night mode I spose.
                                  Is there anything in the pipeline to have this fixed though?

                                  I tried going from steampowered to youtube and the flashbang remains.

                                    @Pebbles1980 remains white? If you open dark youtube tab in the background (when you are on steam page), you should see the dark blue flashbang when you activate youtube tab for the first time. If you continue to open backgrund tabs with youtube pages, the flashbang will remain gray.

                                      I have 2 dark tabs open, Youtube and steampowered.
                                      If I open a new page thats dark also escapefromtarkov.com it still does the white flashbang

                                        @Pebbles1980 my last posts was related only to background tabs, I don't how it works with new pages (where from it takes the background color). Following the logic, when clicking Speed dial tile the flashbang should be dark gray when dark theme is activated, and white when the light theme is active

                                            @Pebbles1980 visit steam page, open any link from steam page in the background (click on link using mouse wheel), when you visit the background tab you should see the dark blue flashbang.
