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.
There was this one from a couple years ago that was about self-driving cars and also sponsored by Waymo. Tom Nicholas made a video which IMO does a good job of covering the problems with that video, and the broader implications of this kind of content on YouTube.
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.
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.
