I have listened to the suggestions of leocg & joshl and have revised my original posting but I seem to have lost the ability to edit my own posts so I'm posting it as a comment instead.
Description: Opera lags when hovering mouse over advertisements and links with long URL's.
Installation Information:
Windows 10; Opera Stable 38.0. I've also tried Opera Beta and Developer 39.0, issue persists. Issue is also reproducible in Ubuntu 16.04; Opera 38.0
Issue persists after a clean install & clean new profile.Steps to reproduce:
Disable ad blockers, including the one built into Opera.
Visit https://youtu.be/t4gjl-uwUHc and watch the video for several seconds, playback should be smooth and fluid, now hover mouse over the advertisement to the right of the video and the video will stutter for a second but then play normally; now rapidly move mouse off and on the advertisement and video will stutter excessively. This video is only one example, you can reproduce this with practically any YouTube video that displays advertisements.
Expected result? Video should continue to play smoothy.
Here's a video of me reproducing the problem, the first three browsers are Google Chrome, Firefox and Microsoft Edge which work as expected; forth browser is Opera which experiences the issue. https://youtu.be/Dr6KpabEfTM
Here's a news article that displays some ads. https://www.theguardian.com/football/blog/2016/jun/12/england-russia-fan-violence-marseille-planning
Keep your mouse off the advertisements and scrolling should be smooth and fluid, now as you scroll make sure you mouse over the ads, scrolling will become jerky and stutter.
Expected result? Scrolling should be smooth when hovering mouse over ads.
My video reproducing the issue, I conduct the same test as before with the same four browsers. It's most noticeable in my first example with the video stuttering but it's still noticeable in this example nonetheless. https://youtu.be/AR5HV-Jbw9g
Same issue happens on another video sharing website. Go to https://vimeo.com/1084537 and scroll down a little until you see the advertisement on the right; now watch the video for a couple seconds and it should playback smoothly, then start rapidly moving your mouse on and off the advertisement and the video will begin to stutter.

This doesn’t happen only on these specific websites, it happens on almost any website when hovering over an ad or link with a super long URL. I understand that I can block ads, but I've made a conscious decision not to and the fact that this doesn’t happen in other browsers means it's a problem with Opera, not the ads. Also, NOT ALL ads cause this issue but it seems like most do.
Link to a picture of the URL that pops up at the bottom of Opera when I hover over that Audible ad seen in my first video.

And this is the full URL of that advertisement…

I just thought of how I can reproduce this problem on this here very forum. What I did was take that Audible advertisement URL and pasted it into a comment 15 times, then I previewed the comment. I refrained from posting it because I know it'll automatically be treated as spam, because that's exactly what it is.
If I can get permission from a forum moderator I'll post it, then anyone here can EASILY reproduce this issue without ever having to leave this forum. It's just a copy and paste of the Audible URL, pasted 15 times, it works perfectly in reproducing the issue I've been describing.
Here's a video of me reproducing the issue using the method I just described. Explanation of what I did in the video, I pressed and held the down arrow key on my keyboard and moved my mouse up and down the URL's as it scrolled. I did this in Chrome, Firefox, Edge and Opera. The first three browsers had no issues, but Opera stuttered like crazy.

Can't reproduce here. The video plays fine no matter what i do.

Anyway, it doesn't seem to be something that severe as it isn't triggered easily by the user.

The problem can easily be reproduced on this forum but I need permission from a forum moderator to post a spam comment. More detail as to why in my comment made at 6:26am which includes video evidence of me reproducing the issue on this forum.

What is your video card? Does the problem happens with hardware acceleration disabled?
AMD Radeon 7700 with the latest drivers; issue happens with hardware acceleration enabled or disabled. I've tested five browsers total on this computer and only Opera exhibits this issue.

I have the same problem. Any link (like an facebook email with a button to see a post), lags the mouse. It doesn´t need to be an ad.

alobpreis last edited byNo need to use ad links. Just consider these sample urls below. Press the down button on your keyboard to scroll at a constant speed and compare the smoothness when the mouse pointer is not over the links to when it is and you move it up and down quickly (basically, making that box below with the url preview quickly and repeatedly appear and disappear).

I noticed that Chrome and Firefox don't display that url preview box while scrolling, and IE either uses a more lightweight algorithm for that fade in/fade out, or just does that in a thread other than the one that handles the page render.

It displayed fast here. No delay at all. I do have a pretty decent system though so maybe it's just a horsepower issue for slower systems?

Well, just holdin' mouse cursor over links area doesn't make scroll stutter, but 'swinging' mouse from neutral area (left side) to links and back makes clear smoothness problems. Same in private window, thus no problems with extensions. O43dev, W10, Intel video.

Certainly not (only) horsepower issue, when other browsers and especially Chrome do not suffer. There must be some (unneeded or badly implemented) internal operation outside page rendering (can be related to displaying url box - of course I can't know, just guess), which locks interface up for some tens of precious milliseconds.
