What is GX Shader?
It's within Settings, says it adds visual effects to webpages.
I'd like to try, before I do and if I don't like it, I need to be able to uninstall. There is not any info on this other than to install a particular "GX Shader."

@zeroshiki - Opera did the same thing to Me.
I was already for a few weeks organizing My 10+++ Years of bookmarks and I was almost finished.
I saw Dot indicating to Update Opera that I was going to do once finished organizing Bookmarks, all of a sudden one night Opera closed then reopened, when I looked for My bookmarks to continue organizing they were all gone on My PC.
I was also signed out from all My other devices but whatever bookmarks saved there is still there. Much of those bookmarks are different.
I did at some point save My Bookmarks on My PC, but those are older and not at all organized. Opera never helped Me after I contacted them. At least they let Me know if they can/cannot be recovered.

!!Damn!! I am mad Crypto Browser will not be supported nor be available for new downloads. So Unfair. Claims Opera One is the way to go. The Jury is out on that.
I Love the Crypto Browser.
Anything to do with Finances - Banking, Crypto, Stocks, Investing, Precious Metals, SEC, Etc. I use that Browser so I am Not Distracted when dealing with Money Numbers.
I separate My Browsers per their use, the way I Web Browse:
Opera One - Online Shopping
Opera GX - Online Gaming
Opera Crypto - Financial Sector
I would appreciate very much if it can be pulled out of retirement and security updates available.

When can that happen?
My 156 year old eyes says its necessary on all Opera Web Browsers.
Opera GX -** I love it for it having that Option.
Opera Crypto doesn't in My opinion need all the Bells & Whistles GX has, but the Dark Mode should've been added in this most recent Update Version 102.0.4880.51.
