Mesa 19.2.0-rc1 available for testing

Fri Aug 23, 2019 1:52 pm

This post may only be of interest to users running GL(ES) applications on a Pi 4 with FKMS enabled.

This week, Mesa have announced a release candidate for the 19.2.0 release, which we would like to switch over to.

https://lists.freedesktop.org/archives/ ... 00536.html

It fixes rendering artefacts I've seen in sauerbraten and those reported here https://github.com/raspberrypi/firmware/issues/1228

piglit (regression tests for mesa) shows too many fixes to list and everything I've thrown at it so far has been better or no worse than the previous build. There are a few regressions, but re-running the failed tests again results in a pass. They may just be failing due to previous failures getting the GPU into a bad state and the test running before it has a chance to reset.

If you would like to try it, edit /etc/apt/sources.list.d/raspi.list and add 'untested' to the line 'deb' line so that it looks like this:

Code: Select all

deb http://archive.raspberrypi.org/debian/ buster main ui untested
If you don't have "ui" in there, that's okay.

Then update and upgrade as usual:

Code: Select all

sudo apt update
sudo apt dist-upgrade

Hi,

Just so it's in one place, this fixed the Chromium issues I was seeing with Openstreetmap maps...

I'm pleased to confirm that this 19.2 candidate fixes the issue with glLogicOp() not being implemented, and makes BBC BASIC work properly again! This is really good news, and I look forward to it being incorporated in an 'official' update.

Hopefully it'll make its way to stable Raspbian once 19.2 releases!

Thanks ShiftPlusOne for the fix.
Selecting an area using Scrot is working fine now.

I've pushed this version into the main repo.

The next 'untested' version will probably be the upstream 19.2.0 release with OpenGL 3.1 patches.

This has fixed the problem with Google Maps repeating tiles and WebGL is actually working well now. I also noticed improvements in visual quality of Doom 3 as well. You guys have been busy and it shows.

One problem that still exists is the Rainbow effect in the Raspbian packaged version of Warzone 2100. Something is still amiss there. I will test other versions of Warzone 2100 to see if the problem is evident with them as well.

I have included a screen capture of the Warzone 2100 with Disco effect. This rainbow glitch has always existed on the Pi 4. It has been something I have not been able to figure out or find any reference to mention of the same problem by others.

Thanks for the screenshot. I've forwarded it on to the powers that be.
