Pretty slow - websites are stuck/freezing

  • Just tried Vivaldi after a while again to see if theres any progress in development - I doubt it after I opened and the page got instantly stuck/slow response/ finally froze.

    @Vivaldi-Team Please develop the simple features like web browsing first before you focus on the fancy ones - thats how Firefox became my favorite browser already in alpha status (2003).

    I can not reproduce such freeze with 1.9 Snapshot (32bit) on Windows 10 x64 Creator.

    Slowness may depend on your hardware and ads on the SpOn page.

    • Do you use extensions in Vivaldi?
    • Do you use Flash Player?
    • After opening vivaldi://gpu what is content of the 1st section?
    • Did opening vivaldi://chrome/settings/search#hardw and deactivation of hardware acceleration and restart of Vivaldi help?

  • Hi, page open in about 2 seconds on low end system but 100Mbit cable.
    Latest snapshot, Flash disabled, uBlock Origin.

    Opensuse Leap 42.1 x86_64
    CPU Intel T4200 4 GB
    GPU Intel GN 965
    xf86-video-intel 2.99.917-6.1

    Cheers, mib

    @SveBjorn: Can't reproduce the problem. Loads quickly and operates smoothly here. (Win 10 Creator Update)

  • Strange, I use Windows 7 - maybe thats the issue?

    Just tried
    It wont load.

    I keep trying.

  • @Ayespy Thanks for checking.
    I will check a few more sites.

  • @Gwen-Dragon I will check my hw and come back to you. Maybe its good to deactivate the hw acceleration.

    @SveBjorn: I think that page works ONLY on Chrome, and no other way.

  • @Gwen-Dragon Looks like my laptop has a view issues here. Is it the hw or are these Vivaldi bugs?

    @SveBjorn Looks ok.

    Do you have two GPU on your PC and one is a Intel GPU? if yes disable the Intel in your BIOS.

  • @Gwen-Dragon Hej, Sorry for the late reply - I have an NVIDIA quaddro K1000M (2GB) - is for most use quite nice and fast, specially CAD. Maybe its too old (5yrs).

    Do you have Flash Player (PPAPI) installed? On some sites Flash ads get crazy and result in memory leaks.
