<![CDATA[Graphical Glitches & Rendering Issues in Big Sur 11.0.1]]>Having a lot of slowdown and graphical issues after updating to Big Sur 11.0.1 on my Macbook Pro 13 (intel i5 2017).

Mainly occurs when I go fullscreen and scroll down a page. It will stutter heavily or when I go back to a tab after not using it for a minute or so, it will be a blank page. Refreshing it is the only way for the site to appear.

I can provide the GPU error report from Opera://GPU if an Opera team member is interested.

Updated Opera today to 72.0.3815.378, which didn't help. Tried Opera Beta and still have the same issue.

Is this what everyone is getting? I've been on Big Sur for a week and this morning is the first time this has happened. I'm not as "technical minded" as some of you are. Is there something that a novice techy can do to fix this?

I have a weird problem, after I switch from the start page to an already open tab, the tab displays a white screen (or black depending on the page design)

Only after a while the view gets fixed and the proper tab content is displayed. Sometimes it also happens to be covered up by some graphical artifacts like white squares covering most of the viewport.
This is very annoying and makes me want to ditch Opera browser and use Chrome instead (which works fine).

That wasn't the case before. For example, in the past I could listen to what was happening in a streaming forum tab while I looked at other tabs. Now, the second I leave the streaming forum tab, the forum stops streaming. I really need the tabs to keep streaming. (It does keep streaming Youtube tabs, even when I leave them, so I don't know what the difference is between the streaming forum tab and a streaming Youtube tab.) It does let me go to another application, however, and it will keep streaming, so it is just the tab switch that causes the issue.

Without a collection of bookmarks, it's difficult to test for the occasional breakdown of pop-down menus, but the occasional problem with Speed Dial being slow to show up also seems to be gone.

Every now and then the display of the webpage freezes and I only see white. Opera does not freeze altogether; I can still change tabs etc.

The problem got Really worse when I connected an external monitor, opted for screen mirroring, and connected to a BigBlueButton meeting. It was basically unusable then; I had to switch to Safari for this.

Especially worse in fullscreen mode.

Anyone find any solutions or is it a Big Sur issue with Opera?
