Direct Win32 API, Weird-Shaped Windows, and Why They Mostly Disappeared

https://warped3.substack.com/p/direct-win32-api-weird-shaped-windows

Article

  • Covers the 90s/00s era of custom-shaped Windows app skins using Win32 SetWindowRgn
  • Explains the pixel-art region-building technique behind irregular window shapes
  • Argues the trend died due to HiDPI, complexity, and shifting UI culture

Discussion

  • Commenters nostalgic but mostly glad weird windows are gone; Winamp cited as best example
  • Electron/React apps seen as the new offender: bloated, inconsistent, OS-mismatched
  • Fun trivia: SetWindowRgn was originally added for Microsoft Bob speech bubbles
  • Technical note: LWA_COLORKEY is easier than manual region-building from pixel runs
