@clavin 为什么把标题改成了英文

[clavin]

@code-small-white I changed the title to English to help other people find this problem and to clarify what the issue is to other maintainers 🙂

@code-small-white if you use a BrowserWindow instead of a BaseWindow that'll fix it in the short term. There's a bigger fix to be made but that'll at least handle it for now!
