A Windows 10 bug: The back story
-
Recently, we reported a huge Windows 10 performance issue to Chromium. They discovered that the problem was caused by a Windows security feature that is useful for protecting applications like a browser.

Let us know updating this article when the patch is actually out, very interesting to know.

I knew that Win10 had added some additional security features, and I like that. I knew there would be some kind of performance impact though (it's always a tradeoff). I didn't expect it to be that high, but if you're spawning 1000s of processes at a time, I guess that' to be expected.
Good article!

I'm using windows 10, 64 bits and I regularly get browser to freeze up

Seems that not only chromium is impacted. -
Nice, this bug would also affect the new Microsoft Edge that will be based on Chromium. The next Microsoft Update on the 2nd Tuesday in May might also have the rollout of 1903 of Windows 10 to some users.

@pseudo555: Also disable the window animations for Windows, a defrag (NTFS struggles even with 1% disk fragmentation). You can also set Windows Explorer to open each window in its own process (increase stability).

I love those kind of articles !!!

Love you!

So wait, does that mean you only recently started testing Vivaldi on Windows 10? Or am I missing something?
Nevertheless, great and very interesting article. Thanks for sharing and please do publish more articles like this one!

No, our QA team do test on Win10, but that is not the kind of testing this article is about.
The testing this article is about, is the automatic testing we do after each build our autobuilder generates after our developers add a new update (This process is called Continuous Integration) . We run many of the same tests that the Chromium team run for each patch they add (I am not sure how up to date it is, but a description of the Chromium system can be found here), our subset is running about 90000 individual, small tests (the various executables contain from a few dozen to more the 27000 individual tests), to make sure we don't accidentally break functionality we need.
The Windows part of this test system is currently Windows 7, but we have wanted to expand it to cover Windows 10, in case there are issues that do not show up on Win7 (and just look at what we discovered when we did )
-
So lets hope Microsoft gets this fixed patch in by May 14, so that Win10 runs better without any slowdowns overall
-
@stpvid1: MS referred to "flighting" it a week or so from now, which means it'll turn up in an Insider build probably a week or two after that. There's no way it's backported into a public build by May 14, assuming they backport at all.

@Yngve Wow... Thanks for the detailed explanation, I really like these tech posts.
So, Could this somehow be related to the slow spawning process of creating new tabs? This is a known problem since the first days of Vivaldi: Just press "Ctrl + T" for a couple of times in a fast manner (or keep the key combination down for a couple of seconds) and you'll feel the slowdown even in systems with faster CPUs (although it's a bit faster on newer builds), but do this in Firefox and you'll see that all the tabs spawn pretty fast and there is no slowdown like on Vivaldi.
-
@yngve Thanks for the clarification, I appreciate it and also that you now run automated tests on Windows 10
-
@archive1 Same here!
-
In tiled tabs, if one of the tabs is the one where you need to type something (Todoist, Evernote, Word online, etc), there is a serious lag when typing. This is really annoying issue. I already reported this, but no answer to date...Please fix this.
-
@veljapo This seems to be the same issue as the one where there is lag when a tab is moved to a new window. I too would really like to see this fixed, as it also affects scrolling makes multi-tasking very difficult.
-
Will this CFG issue affect us if we have CFG or Windows Defender switched off? How does it manifest - just as lag?

There has been an update today with this fix mentioned: "Addresses an issue in Gdi32full.dll that causes an application to stop responding" https://support.microsoft.com/en-gb/help/4495667/windows-10-update-kb4495667
I guess it is included in it then, or?
