Full KMS - #Kivy with Mesa

[kuzeyron]

The steps are easy.

sudo apt-get install libsdl2-dev libsdl2-image-dev libsdl2-mixer-dev libsdl2-ttf-dev \
   pkg-config libgl1-mesa-dev libgles2-mesa-dev \
   python-setuptools libgstreamer1.0-dev git-core \
   gstreamer1.0-plugins-{bad,base,good,ugly} \
   gstreamer1.0-{omx,alsa} python-dev libmtdev-dev \
   xclip xsel -y

sudo pip2 install Cython==0.25.2 && \
sudo pip2 install git+https://github.com/kivy/kivy.git@master

And then running @frankgould's code
I have already once edited the code to be running better. I don't think it matters what code you are using. As long as there are Fade in/out or Animations it should give you the same errors.

But if you try it. With the default mesa version that is set it will talk about Memory allocation errors and so on. FBO shows more often up if it's the Default drivers. The Memory allocation part show up in the dmesg and it freezes the entire Desktop on the Pi(3B+).

Running mesa upgrade through "git clone" makes these errors to stop showing up.
It can run it for hours without a error. But then going back to the original mesa version. It crashes.

If the current VC4 drivers in Mesa master work, then there's not much I can do for you. Raspbian has ancient software, and I have no control over their update schedule.

Ahaa okay! Thank you anyway for your time!

I have been working with a team of Kivy and Mesa driver engineers who have identified that Raspbian graphics need to be updated and a new version tested and released. Below is more information about this issue that was first reported on Kivy Github Oct 7, 2016, link below.
kivy/kivy#4662

Below is the Final Word from one of the engineers:
What is needed to fix this would be a updated VC4 (VideoCore IV) and then update the graphic drivers. I saw a VC4 version here on Github but latest changes are about two years old.

This is a dead end unless the foundation themself (Raspberry Pi) marks this as important. When I've been testing, I've tried using Gl4es and Mesa.

Below are the issues we've reported and the support responses:

Because of this Kivy driver problem, I tried to migrate my app to pi3d but here's what I reported in May 2018 and have not had any responses:

Where should we go to request Raspbian be scheduled for graphic drivers updates, tests, and release?
