Page freeze half second when scroll down when set "Number of raster threads" more then 1.



  • Hi,

    When update to last stable version I have experience about page freezing about 0.5 second when scroll down or up with long pages that never happen before update and I found out when set "Number of raster threads" flag to 1 is stop this freeze problem; default option is the first place that cause page freeze, I try to set it to 4 and as number of my cpu threads but it still freeze.

    My Vivaldi 1.10 Stable x64 does not start with your flags. So not reproducible.
