CPU utilisation up from circa 2% to 80% after update from 1.13 to 1.14 with same session

  • Same pages as was in 1.13 opened before update and after around 20 seconds CPU utilisation (i4770) goes up to 80% and stays around that number.

    Vivaldi manager shows that high CPU utilisation is not restricted to one tab but affects all (or all most) of them in different degree.

    I have Windows 7 up to date

    Anybody has experienced that?

  • I'm waiting for the slipstreamed version of 1.14 before upgrading my main install, but I do have the dev build on the side, which should be the same thing.

    I haven't seen any unusual CPU action though. Are there any specific sites that you know of that do this, as opposed to others?

    @ksus May be a problem with graphics?
    Open vivaldi://gpu and check for red issue in Graphics Feature Status section.

    Or worse a BIOS/Windows update related to current Intel firmware/CPU security.

  • Isn't he talking about a difference from 1.13 to 1.14?

  • Moderator

    @rseiler may be because of new graphics code in Chrome 64 and resulting in a GPU blacklist. Slow down can have many sources.

  • @rseiler

    No. No specific sites.

    It is generaly strange because it starts to utilize 80% of CPU suddenly after some time o work (It is going from lets say 2 or 5% to 80% in a second). I cannot find any similiarities in my actions when it happens other then use of Vivaldi browser (it not happen when browser is in background) and memory utilisation going up but in Windows resources monitor it is still free memory (light blue) when it happens.

    What's more - closing most of windows (eg. 90% of them but not 10 or 30 or 40%) couses drop of CPU utilisation to normal value. But when I reopen most of them again situation is repeating - not on any specific window or tab openning but just when memory goes bigger.

    I reported this as a bug, but because nobody has same problem doubt to see solution from Vivaldi Team


    Disabled Features: native_gpu_memory_buffers
    Disabled Features: checker_imaging

    I'm checking in google what's that.

    @ksus vivaldi gpu looks like ok.

    Can you check in Vivaldi taskmanager (SHift+Esc) what consume so much?

  • @gwen-dragon

    Dont know what the units are

    Browser - around 160 - 190
    Page in background - some 2/3 of the Browser
    Single pages usually 1.5. Some up to 15 but I have plenty of them

    I remeber in 1.13 same session has probably 5% on average CPU utillsation

  • Moderator

    @ksus I hoped you woudl be able to see if a extension or special page consumes much more than others.

  • @gwen-dragon

    I hoped too. But if I could find such I would just close it. But thanks for help attempt.

  • In trying to replicate the memory leak issue, I accidentally replicated the CPU issue. Can you do it without a second window?


  • @ksus Any difference with the first maintenance release of 1.14?

  • @rseiler Sorry but after my data lost last time I'm to afraid to install new releases. After system loss triggered by problems with Vivaldi I have switched of update notifications, restored system from Clonezilla clone and staying for undefined period of time with Vivaldi 1.13. If there will be some really briliant new feature in some new release will again consider update after careful reading of the problems reported on forum.

  • Guess this is related. Cpu was around 36% first, then it dropped to 0 as ram kept on increasing, after that it dropped ram usage and was frozen.

    Would love to throw logs but no idea where they are.

    EDIT: ATM it's working fine.. what is currently different, i had speed dial opened in second window, as well as webpanel opened for todoist (doubt it's cause) also closed khan academy but i also doubt it's likely to be the cause..

    I'm guessing speed dial or webpanel related.

    edit: also few times i had vivaldi and rainmeter crash at the same time as weird as it sounds..

    Which logs?
    Last Crashdumps? At %LOCALAPPDATA%\User Data\Crashpad

  • K thanks can I submit hem but any secure way ? I'm guessing those are mem dumps, wouldn't want to share any sensitive info.
