No show after start
Very often I have the problem that Vivaldi does not show any window after start. Even after force quit and restart it is not better. Only solution: Restart macOS completely.
Have you tried the shortcut
cmd nfor new window?
@VillageHero Wow, that's not typical at all. Just curious... why the Force Quit rather than exiting Vivaldi with either
Vivaldi / Quit Vivaldi? Did Vivaldi lock up to the point that you could not exit it in any other way? Force Quitting should only be used as a last resort because it doesn't give an application the opportunity to exit gracefully in a controlled manner. With Vivaldi, this can corrupt your profile and cause a ton of other problems.
If you check "Use Native Window" in the Appearance settings, do you still get into a situation where the Vivaldi window does not open or render on launch?
Still have this behavior with the latest version. It occurred this very moment - suddenly Vivaldi did not load any new webpages. I closed it via Cmd+Q - re-opened it and it did not load any webpages or showed even the Preferences menu entry (all menu entries are greyed out). In this state I can close it again via Cmd+Q - but it won't load any pages until re-start/logout. No hanging processes were shown in Activity Monitor.
What's strange: Somehow also Chrome seems to behave strange when this occurs. It's a lot slower and hangs sometimes.
I switched now to native window behavior and will observe further.
@VillageHero From your initial post, I thought that perhaps Vivaldi's window management had gotten into a weird state; if so, toggling "Use Native Window" should force it back into a good state.
However, you just mentioned that you're also experiencing similar problems with Chrome... Do you have any extensions installed?
Are you experiencing any other issues with your network or operating system/hardware? Do you have any non-Apple devices installed? Do you have any security software installed on your Mac? Lastly, are you running into any issues with Safari?
@xyzzy Extensions, yes. But those should not interfere? The only one I think could be responsible is Signal Messenger as App. But I am always opening this with Vivaldi. Nevertheless I deactivated it in Chrome and will observe further...
Answers to your questions:
No network issues. I got a Cherry MX keyboard. And a Logitech mouse. Security software: BlockBlock (but I also deactivated it for testing the issue).
No issues with Safari or Firefox.
@VillageHero Vivaldi is not Google Chrome. Most extensions work fine in Vivaldi but not all. Some very Chrome-specific apps don't; some cause really weird things to happen. Users have reported problematic extensions here: https://forum.vivaldi.net/topic/8129/list-of-incompatible-extensions
Whenever users run into bizarre problems, the first step is to disable all extensions to see if the problem goes away. (Often it does.) Then re-enable extensions one-by-one until you find the one(s) causing problems.
What's more unusual is that you're having issues with Chrome as well. Security software can do that. So can extensions -- not all of them are safe or trustworthy.
The reason I asked about non-Apple devices is that some have out-of-date or badly-written device drivers. Generally speaking, these can de-stabilize the OS. There can be issues when a browser interacts directly with third-party keyboard and mouse drivers. Chrome and Chromium-based browsers (like Vivaldi) also support WebUSB, which potentially could have interaction issues with devices and their device drivers as well.
The fact that you also need to reboot your system to clear/resolve problems also implicates hardware/software/drivers that interact with macOS at a low level as well.
@xyzzy I tried with native windows. No success. Had this case in the current minute: Vivaldi showed just the Menu - but not any window. Tried it also with native - without success. An logs or reports where I can look further?
@xyzzy Ok, I removed some extensions and also removed BlockBlock from system. Still there systemwide: Karabiner-Elements, Bartender, Oversight (just for you to know). Are there any possibilities to find out what's going on - logs, incidents in system etc ?
@VillageHero I'm honestly not sure what to suggest at this point apart from first cleaning or resetting your Vivaldi profile just to make sure that the configuration files have not gotten corrupted: https://forum.vivaldi.net/topic/10388/refreshing-or-cleaning-your-profile
Vivaldi runs fine on my system -- no weird issues whatsoever -- but I'm still running OS X 10.11.6, I don't do any extreme, non-standard or unsupported enhancements or customization, and I'm very careful not to de-stabilize the base OS. Like many Vivaldi users, I use uBlock Origin and uBlock Origin Extra. Unlike most users, I'm often TRYING to break Vivaldi.
Vivaldi uses standard system logging and the logs can be viewed and searched with Console.app. Even relatively benign stuff gets logged so hopefully you'll see something that might be helpful in your troubleshooting.
