Re: Mouse Issues

You really need to give more detail than that. For starters, what operating system are you using, what wireless mouse is it, and what steps have you taken to connect the mouse to the Pi?

Re: Pi 4 with Buster - No hardware acceleration for Video/WebGL in Chromium?

If the cursor was in the normal state and then transitioned to the animated "loading" state, there would be one or two frames when the cursor has been offset to accommodate the loading state, but the cursor still appears as the normal state.

Scratch 3 on the Pi4 runs very well, we've been testing for some time. Once the GPU acceleration fix is released it will be even quicker.

Chromebook OS runs Scratch 3 EFFORTLESSLY on Pi 3B. Can we improve chromium?

I tried out Scratch 3 on the latest image of chromebook OS for Raspberry Pi , to see if Scratch 3 would work better than it currently does on Raspbian. Well, it does! In fact, the graphics performance was equivalent to my $400 windows laptop! On Raspbian: (slow and laggy) https://s3.gifyu.com/images...

My Raspberry Pi 3 lives in a desktop computer case. It boots from a 3.5" 1TB hard drive. Because the hard drive takes a while to spin up at boot, I have a 4GB microSD card with only the boot partition on it. This configuration has proved to be very trustworthy, but it has horrible random read/write....

Re: Issue with video calling

The Raspberry Pi 3 is 64 bit. The operating system is 32 bit. Essentially half of the processor is never used. The first and second of those sentences are true. The third one is not. Are you referring to the support circuitry? Or are all of those 'unused' transistors actually used for something?
