Addresses reported flickering and rendering problems on ARM64 devices running Windows 11 25H2 by implementing ARM64-specific rendering defaults, build configuration fixes, and redraw optimizations. Rendering fixes: - Default to SC_TECHNOLOGY_DIRECTWRITERETAIN on ARM64 to preserve back buffer between frames, avoiding blank flashes with Qualcomm Adreno GPUs and Win11 25H2 DWM compositor changes - Wrap MsgThemeChanged() in WM_SETREDRAW FALSE/TRUE to suppress N intermediate repaints during heavy theme/DPI transitions - Add WS_EX_COMPOSITED to main window on ARM64 for system-level double-buffering - Remove RDW_ERASE from DarkMode ListView/TreeView RedrawWindow() calls to avoid background erase flash during theme changes Build configuration fixes: - Add _WIN64 preprocessor define to Scintilla, SciLexer, Lexilla ARM64 configurations (was missing, could cause 32-bit code paths) - Add TargetMachine=MachineARM64 to all ARM64 linker sections across Notepad3, Scintilla, SciLexer, Lexilla projects - Add CETCompat=false to Scintilla and SciLexer ARM64 configurations (CET is x86/x64 only, not compatible with ARM64) Platform code improvements: - Add _M_ARM64 detection for GrepWin binary selection (ARM64 was silently mapped to x64 binary via _WIN64 check) - Add NP3_BUILD_ARM64 helper macro in TypeDefs.h for future ARM64-specific code paths - Document RenderingTechnology setting in Build/Notepad3.ini with per-resolution override syntax and ARM64 troubleshooting tips Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
Add comprehensive ARM64 section to both CLAUDE.md and copilot-instructions.md covering: - Architecture detection (_M_ARM64 vs _WIN64 distinction) - NP3_BUILD_ARM64 helper macro in TypeDefs.h - ARM64 rendering defaults (DirectWriteRetain, WS_EX_COMPOSITED) - ARM64 build config requirements (CETCompat, TargetMachine, _WIN64) - GrepWin x64 emulation on ARM64 - Theme change flickering prevention (WM_SETREDRAW lock) - ARM 32-bit not supported (solution config maps to Win32) Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
