Weird browsing lag with Opera 28

  • Just do the 'Graphics Feature Status', 'Driver Bug Workarounds' and 'Problems Detected' sections if that makes it easier. Below you'll see my output. Its fairly standard for a Windows machine.

    Use four spaces at the beginning of each line to indicate a block of pre-formatted text, such as code samples.

    Example:

    Graphics Feature Status
    Canvas: Hardware accelerated
    Flash: Hardware accelerated
    Flash Stage3D: Hardware accelerated
    Flash Stage3D Baseline profile: Hardware accelerated
    Compositing: Hardware accelerated
    Multiple Raster Threads: Enabled
    Rasterization: Software only, hardware acceleration unavailable
    Threaded Rasterization: Enabled
    Video Decode: Hardware accelerated
    Video Encode: Hardware accelerated
    WebGL: Hardware accelerated
    
    Driver Bug Workarounds
    clear_uniforms_before_first_program_use
    exit_on_context_lost
    scalarize_vec_and_mat_constructor_args
    texsubimage2d_faster_than_teximage2d
    use_current_program_after_successful_link
    Problems Detected
    GPU rasterization is blacklisted on non-Android: 362779
    
    Disabled Features: gpu_rasterization
    Always call glUseProgram after a successful link to avoid a driver bug: 349137
    Applied Workarounds: use_current_program_after_successful_link
    Some drivers are unable to reset the D3D device in the GPU process sandbox
    Applied Workarounds: exit_on_context_lost
    TexSubImage2D() is faster for full uploads on ANGLE
    Applied Workarounds: texsubimage2d_faster_than_teximage2d
    Clear uniforms before first program use on all platforms: 124764, 349137
    Applied Workarounds: clear_uniforms_before_first_program_use
    Always rewrite vec/mat constructors to be consistent: 398694
    Applied Workarounds: scalarize_vec_and_mat_constructor_args
  • lando242 May I ask a question. I have used Opera for many years, but am not a computer expert by any means. I am also experiencing the problems mentioned here. I am not able to find the Opera profile folder to see if I have the files with 'sessions' there! Can you help me navigate there please?

  • Opera Menu > About Opera. It says the location of the profile folder near the bottom of the page.

  • Ditto, same problem, except my lags are about 3-5 seconds long every 20-30 seconds. Opera is now impossible to use.

  • Any fix yet?

  • Did you try the deleting of the sessions files?

  • What is the function of the session files?

  • Read the first reply to this thread, that should cover it.

  • Did you try the deleting of the sessions files?

    When I go to the AppData\Roaming\Opera Software\Opera Stable there are no files in that folder with "session" in them
