I tried reinstall but it just made it worse this 63.0.3368.66 version is not stable at all!
Synchronizing does the same crash and even installing addons!
Sorry but this is really bad! I jumped back to Ihre Version: 63.0.3368.53 but jeah auto update f... it up again!

I got the new Opera Version 63.0.3368.66 yesterday and now i cant watch youtube or any player in fullscreen.
If i get out of the Fullscreen Video all Opera does is crashing and it is really getting annoying since i am used to watch my videos in fullscreen mode!
or is there a new feature with that version that might does that because something might or might not be compatible or creates crashes...?

Hi
I got a problem, i always use my controller to use the mouse but after sometime i cant use it anymore after opening opera(only when the window is active!)

Also it work with opera before in the versions before!(dont know when it changed!)

I would like to know if there is a way to deaktivate it because its really annoying!

the program or better said programs that interact with the mouse dont work if the browser is active i tried also some autoclicker just for fun and i couldnt use it only on my desktop or other programs!

If someone knows what or how i could disable this i would be really glad!

Also thanks for reading my kauderwelsch english!

no one else a problem with it?

i got the sams problem only i got it by going in fullscreen and out and my complete brwoser is freezing from time to time if i waited thoes 1-5 min to load it in/out

but i use now the pop out function(button on the top middle bit of the video) on youtube so its ok but not the best

i also looked in the developer and beta of this browser and its not fixed(even thoug they said this updete waht the normal opera got would fix it...) in both of them...

my operating system is windows 10

Hi
As you can read from the title i cant really use Fullscreen mode for youtube or anykind of player anymore because it needs 1-5 minitues to load it in and after watching those 1-5 minutes in 20 sekonds it is completly normal if i wan to close it i also need to wait that amount of time!

And if i use the popout funktion it easily plays the video without hanging or anything but still like the fullscreen mode better...

This is really annoying and it just happen today with the new update...

Also it says sometimes that a plugin is freezing or slowind my pc down even though opera is the only slow and freezing program...

Browser: Opera (Stable version)
Also tried: Opera Beta, Opera Developer

Yesterday i could do everything in a sekond now minutes...
oh and i also tried if any other browser like Firefox or Chrome got the same problem but they open it in fullscreen in seconds!

Sorry for my bad english grammar not really a fan of it,,,^^

wow nice now i cant watch any Videos at all anymore im sorry,
but i warned you guys before that youtube Vidoes or any Vidoes still freeze if they get into fullsceen!
your newest update that should have solved the problem didnt do anything for me and many other people!

I need around 1-2 minutes to load in fullscreen and also out of it!this is really annoying!

Elsewise i really like those new features but i would also like to watch Videos in fullscreen!
