Radeon Palm vdpau broke with update bionic

[hfdskjfdskjfdsuiqöewrö]

Ubuntu: Ubuntu 18.04.2 LTS (Release: 18.04)
Graphiccard is a AMD Radeon Palm using the r600 driver.

Two days ago i installed the updatet mesa packages for bionic: from 18.2.8-0ubuntu0~18.04.2 to 19.0.2-1ubuntu1.1~18.04.1
My Kodi-Mediacenter doesn't play videos with vdpau-hardwareacceleration anymore. It just hangs and crashes after a few seconds.

I identified two workarounds:
1. Deactivating vdpau
2. downgrading of these packages helps, but the screen is flickering, assumingly because of the combination of 19.0.2-1ubuntu1.1~18.04.1 and 18.0.0~rc5-1ubuntu1 packages:
libgl1-mesa-dri:amd64 to 18.0.0~rc5-1ubuntu1
mesa-vdpau-drivers:amd64 to 18.0.0~rc5-1ubuntu1

I am not sure, where the problem was. But after new installation of all mesa packages, it worked.
