预检清单

Electron 版本

29.1.1

您正在使用的操作系统是什么?

其他 Linux

您正在使用的操作系统版本是什么?

Linux archlinux 6.7.9-arch1-1 #1 SMP PREEMPT_DYNAMIC Fri, 08 Mar 2024 01:59:01 +0000 x86_64 GNU/Linux, KDE Plasma 6 Wayland

您正在使用的架构是什么?

x64

最后已知的工作 Electron 版本

我检查了尽可能早的 Electron 17,但找不到一个不会崩溃的版本(由于其他原因,无法在较早的版本上正确使用 Wayland)

预期行为

screen.getCursorScreenPoint() 在创建 BrowserWindow 之前不应发生段错误。如果无法实现,则应抛出 JavaScript 错误,并相应地更新文档。

实际行为

当我使用 Electron 29.1.1 运行以下代码时,应用程序会因 Segmentation fault (core dumped) 而崩溃。gdb 在段错误处返回以下回溯:

#9  0x0000000000000000 in ?? ()

在 Xwayland 下运行时(没有 --ozone-platform-hint=wayland),没有发生崩溃。
