The issue is present on Windows 10 and 11, from Adrenalin 23.12.1 to 24.3.1 for integrated graphics on Ryzen 9 7950X.
The issue is not present in 23.11.1 or for system with only discrete graphics like Radeon RX 6900 XT (other CPU).
Steps to reproduce:
1) Install clean Windows 11 23H2 on system with Ryzen 9 7950X and no discrete graphics, with no internet access.
2) Check that the issue is not present on clean system:
run FindZombieHandles.exe
run in cmd FOR /L %i IN (1,1,1000) DO cmd /c echo %i
run FindZombieHandles.exe again: the same amount of zombie processes.
3) Install whql-amd-software-adrenalin-edition-24.3.1-win10-win11-mar20-rdna.exe
4) Repeat step 2: now all 1000 spawned processes turned into zombies with no apparent owner.
The system with affected drivers becomes completely unusable for me after some time: the system consumes dozens of GB of RAM outside of any apparent process, as I need to run many short-lived processes.
I'm not sure is there any other resource leak in drivers, but the described one is apparent.
