Flickering while opening a Flash based site on openSUSE leap 42.2
-
Every time, I tried to open a Flash based site; the page starts flickering. I am using Vivaldi(latest stable) on Fedora (25) and openSUSE. Flickering occurs only on openSUSE; everything seems to be fine on Fedora. I just wonder if it is because of the Flash player as openSUSE provides a distro based Flash player while in Fedora I'm using adobe-release repo. Example sites on which flickering occurs:

Some more details; I have both chrome and vivaldi installed; the problem occurs only on vivaldi and in a private window.
Here are the details of my flash installation:Vivaldi: 1.8.770.54 (Stable channel) (64-bit)
Revision: e2cd2e0f9cc4bf56968f7869149c05302db06306
OS: Linux
JavaScript: V8 5.7.492.72
Flash: 25.0.0.127 /home/mahsan/.config/google-chrome/PepperFlash/25.0.0.127/libpepflashplayer.so
Command Line: /usr/bin/vivaldi-stable --always-authorize-plugins --disable-translate --enable-blink-features=ResizeObserver --mark-non-secure-as=show-non-secure-passwords-cc-ui --flag-switches-begin --flag-switches-endA related question why vivaldi is saying 'show-non-secure-passwords-cc-ui in the command line arguments?

@ahsan I do not have that problem at all. I have tried on both Arch and the Ubuntu based KDE Neon. I have tried with both release and latest development build. I think this is an incompatibility issue with you graphics or it's driver. A detailed bug report at https://vivaldi.com/bugreport would be good with as much detail as possible. I see you have indicated you are using "Linux". I think we need more detail than that
​//Christian - Thank you for using Vivaldi!

@ahsan Friend of mine also runs openSUSE Leap so I've a good reason to have him install vivaldi and test this for you on another machine but this may take a day or two.

I had the issue, the solution was simple:
Put this in the address bar:
vivaldi://chrome/settings/search#hardware
Then unclick "Use Hardware acceleration when available and restart.
Worked for me in Mint Cinnamon 18.1

Thanks everyone; disabling 'hardware acceleration' solves the issue. However, I am curious to know why do I need to disable the hardware acceleration and what's the impact of it.
Searching through the chrome settings (chrome://settings/search#hardware) I found that hardware acceleration is checked. I'm curious to know why the flickering does not occur in chrome even though hardware acceleration is checked.

@zaibon Tested this yesterday and turning off hardware acceleration fixed it on leap.
