研究方向
Investigate the freeze when running `flameshot screen` or `flameshot full` by comparing the code paths for `flameshot gui`. The issue likely lies in the save dialog rendering or event loop handling. Start by examining the screenshot capture logic in `src/core/` and the dialog creation in `src/utils/`. Look at the comments for any clues about X11 vs Wayland or NVIDIA driver issues. Try to reproduce with a debugger to see where the main thread blocks. Consider testing with different window managers to isolate the problem.
