Issue Description:
I'm relatively new to Raspberry Pi development and have encountered an issue related to recent firmware or package updates affecting GPU driver performance.
I am building a custom Raspberry Pi OS image using pi-gen. Specifically, I customize only stage3 while keeping stage0, stage1, and stage2 unchanged.
After applying updates released on 2025-03-05, I noticed significant performance degradation on my Raspberry Pi 5 (ARM64). The symptoms include:
- Noticeable screen lag
- Visual tearing
- Poor graphical responsiveness, as if proper GPU acceleration is missing
Upon investigation, I've confirmed that the GPU driver appears loaded according to the X log; however, the issue persisted.
Further debugging revealed that the problem originates specifically from recent updates to Mesa-related packages. As a temporary workaround, manually reverting the Mesa packages to the previous version resolved performance issues.
Temporary Workaround:
If anyone else encounters this issue, I used the following script as a temporary fix to downgrade the problematic Mesa packages since the older packages are no longer in the current APT release list:
Additional context:
Here are the packages installed at pi-gen stage3:
