Try using the Vivaldi (64bit) browser for a while, use the mouse wheel to scroll up and down in various sites. i'm only playing with it for reading newspaper sites like the guardian, telegraph, huffington, metro and some of those sites hate being scrolled via the mouse wheel (though no problem in other browsers) If the pages start to flicker when scrolling then exit the browser and watch the desktop do the same for a while. Admittedly, vivaldi is a work in progress but i have no idea what to report as i can't get it to do this every time. Just wish i could record it to show it happening.

i'm concerned that it affects the desktop after the browser has closed. I'm using kwin/plasma 5 - latest tumbleweed versions

Tw up-to-date and nvidia 355.11

Dl'd for trial and do not find the problems you cite. Scrolls smoothly, has caused no crashes after about one hour.

Appears very snappy although the interface is rather different.

This was vivaldi-preview.

i'm using nv. the problem shows itself with the scroll bouncing back up immediately after you scrolled down but some of the other tabs are not affected by it. i'm just wondering if its a dodgy advert on the page as all these newspaper sites are advert driven. -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

Hello Ian,

I am observing a similar behavior since a while. Could you try restarting the kwin session. (Or rather: Start a new one with "kwin_x11 --replace"). If the problem vanishes, I would be quite sure that it is the same problem.

The effect on my PC is about the same one like in this video (not made by me):

https://www.youtube.com/watch?v=d_zVI_yY6r0&html5=1

Till now I wasn't able to narrow it further down. Sometimes I had the impression that VLC is able to cause the problem. But it is not the only application.

It may be interesting that I noted the same behavior on an Arch Linux installation on the same PC. To be exact: I reinstalled the PC because I hoped that plasma on OpenSUSE would be slightly more stable.

Eventually this problem depends on the used graphics hardware?

I have a Radeon card. hwinfo --gfxcard gives the following model: Model: "ATI Turks XT [Radeon HD 6670/7670]"

I'm using the open source radeon driver.

It looks like it's a redraw issue. Probably related to double buffering or the like. When I've experienced similar things in the past, with Compiz (granted, plasma isn't compiz) I managed to work around it by picking other rendering methods. So, go to desktop effects configuration and try playing with the advanced tab. -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

logging out cures the problem for me.

that restarts some more applications. But I wouldn't rule out that it is the same effect. You might want to try what Claudio Freire and Wolfgang Bauer suggested for me: Change the rendering methods in System Settings -> Display and Monitor -> Compositor.

Kind regards,

Christian Thanks Christian. I might try that but it only happens when vivaldi screws up. i just thought i'd mention it as it continued happening during that session after vivaldi had been closed down. I thought it might be screwing with plasma in some way and

Did you report it to vivaldi as it is much more likely a problem with their software unless you witness similar problems with software provided by opensuse? re: "when vivaldi screws up".

i have, i was concerned that it "appears" to infect the desktop so i thought i'd mention it. -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org
