Mouse cursor jumping with openGL enabled - RPI3

Short version of my question: Why does the mouse cursor jump around while switching states when GL driver is enabled? Details below: I enable GL desktop driver (full or fake KMS) in Raspbian desktop (Stretch or Buster) on a Pi3. 2019-07-15-171154_1280x1024_scrot.png After a reboot, the mouse cursor ...

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. I caught this phenomenon on video: https://s3.gifyu.com/i...

I love Raspberry Pi, but I have always felt uncomfortable with Raspbian Pixel's appearance.

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...

Any way to increase random IO on hard drive?

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?
