<![CDATA[Weird browsing lag with Opera 28]]>I've been using Opera for a month and it's been quick and working great. But the past few days I've noticed a very slight lag at times when browsing. Here's what I notice:

  1. A very slight delay when typing on forms on websites (like this one)

  2. HTML5 elements on websites are very slow and laggy

  3. YouTube videos are UNWATCHABLE. They lag, stutter, and run in slow motion and the audio doesn't match with the words. Very bizarre.

This seemed to happen out of nowhere, I think there was an update so I'm not sure if that is what caused it because I had no issues before.

I've already tried fiddling with disabling hardware acceleration and all of that and it didn't fix anything.

My specs:
Windows 7
Intel i7-3770K CPU @ 3.50 GHz 3.50 GHz
16 GB RAM

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

Opera is now impossible to use.

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?

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:

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

Go to opera://gpu/. Post results. Be sure to use markdown so the forum doesn't gobble it up.

I'm trying to paste it but not sure how to use the markdown to properly display all of it (it's long). And right now it looks like a jumbled mess when I try to paste it here

With Opera not running fo into your profile folder and delete the three files that starts with 'session' that you find there. Just a heads up, this will clear any webpages that you had open the last time you exited the browser so you wont be able to continue where you left off. Bookmark them before you delete these files if you need them. Does that fix the problem?

I thought this would be the cause since someone else on here said it fixed it. But when I go into my profile folder there are no files with 'session' in it
