I’ve been using Linux off and on again for the past decade.
The original reason I used Linux was because as a kid I got stuck with whatever old laptop was laying around, so my dad would install Ubuntu to make it usable.
When I built my first computer a couple years ago and started using Windows 10, that’s when Windows stopped working for me. Nothing made me want to switch more than when the major Windows 10 updates broke my software every 6 months.
Its almost certainly a VirtualBox issue. I would suggest changing the graphics controller to one of the other options. I have my Linux VMs set to VMSVGA as that has had the fewest bugs.
If it makes you feel any better, VirtualBox 7 has had quite a few regressions specifically with the graphics stack and has caused problems with all of my VMs. My Windows 11 VM only rendered a black screen until 7.0.10 and all my other VMs are still using old versions of Guest Additions because of the instability with the newer versions.
The TLDR summary is that AVIF was going to be the next generation standard for image formats but when JPEG-XL released with a near identical feature-set, better quality compression, and backwards compatibility with JPEG, the tech world put its support behind JPEG-XL.
Naturally, Google as one of AVIF’s creators was unhappy that the standard they control looks like it will lose the format war and so they decided to use their web monopoly to kill JPEG-XL in the cradle by killing support for it in Chrome around a few months ago.
While this has slowed JPEG-XL’s momentum by a lot, even the other co-creators of AVIF like Apple, Meta, and Microsoft are still putting their support behind JPEG-XL and it seems like they would rather force JPEG-XL adoption themselves than go back to AVIF.
It says in the article that triple buffering only activates if your GPU struggles to render the desktop. That means old and weak iGPUs are getting this. For your desktop card nothing should change.
