[REGRESSION] Painter 12.0+ crashes on project init with RTX 4090 — 11.1.3 stable, 12.0.0/12.0.3/12.1.2 all crash

Confirmed regression: Painter 12.0+ crashes on project init with RTX 4090

A/B version test completed on identical system state:
- 11.1.3 (Feb 2026): Stable — Adobe sample projects open and run correctly
- 12.0.0 (Mar 2026): Crashes immediately on project initialization
- 12.0.3 (May 2026): Crashes immediately
- 12.1.2 (Aug 2026): Crashes immediately

Regression boundary: The crash is introduced in the Painter 12.0 branch, not in later patches or external system changes.

Crash signature:
- Faulting module: nvoglv64.dll (NVIDIA driver 591.74; also reproduced on older driver versions)
- Exception: 0xc0000409 (STATUS_STACK_BUFFER_OVERRUN)
- Fault offset shifts with driver version, consistent with the crash occurring inside the NVIDIA driver but triggered by Painter's renderer/project initialization

System: RTX 4090 24 GB, Windows 11, Adobe sample projects, default preferences, no custom libraries. HAGS at system default (enabled). Hardware and BIOS verified stable.

Isolation done: DDU clean driver installs, preferences reset, RAM tested, sample projects used. The only variable that changes the outcome is the Painter version.

Request: Investigate and fix the renderer or project-initialization regression introduced in Painter 12.0.0.
