Textures, Background Colours Won't Stay

So…the crickets have become deafening. I’ve run across some more info that I need opinions on because I’m running out of time. If it becomes undoubtedly clear that this laptop will NOT be suitable for working with SU, I have only 10 more days left during which I can return it.

I followed a link in the thread “Recommended laptop for SketchUp in 2019,” but the only info I could find that [possibly] comes closest to what may be applicable fell under “SketchUp Pro - System Requirements.”

If these recommendations are applicable to my use…then I have perhaps identified one issue…an issue I never expected in light of the fact that this new laptop is a “gaming” machine, and I was advised that it would be more than adequate for drawing and creating work with multiple layers. This so-called gaming machine does not have hard drive accelerator. I gave this no thought since RAM on this laptop can be increased and it has an NVIDIA graphics card (the reasons I chose it over other considerations) - was mistaken in thinking that more RAM would/could make up for that?

Can anyone advise whether or not the recomendations for SU Pro are applicable for Google SU-8 and Trimble SU-Make 2014, and that that one issue is in fact what the problem is as highlighted in the video linked in my OP?

NOTE: This may also be helpful – I took a dive off a technical cliff and removed the checkmark by Use hardware acceleration (since this laptop doesn’t have hardware acceleration) in OpenGL Settings thinking that would improve the situation…instead, it limited use of my space mouse to zooming in and out only.
