背景
在使用 GGUI 绘制图形后，我想用普通的 alt+Tab 从图形窗口切换到其他窗口，这时窗口会退出并报错：
Assertion failed: (key_mod_flags == 0 || g.IO.KeyMods == key_mod_flags) && "Mismatching io.KeyCtrl/io.KeyShift/io.KeyAlt/io.KeySuper vs io.KeyMods", file C:/Users/buildbot/actions-runner/_work/taichi/taichi/external/imgui/imgui.cpp, line 7234
如下一份很简单的按下 ESC 键退出窗口的代码中，偶尔也会报错；如果按一次 alt 没反应，多运行几次多按几次就会发生同样的错误 
import taichi as ti
ti.init()
window = ti.ui.Window('TEST', (768, 512))
while window.running:
for e in window.get_events(ti.ui.PRESS):
if e.key == ti.ui.ESCAPE:
window.running = False
window.show()
不过若将 while 循环中的控制代码全删掉，只留下 show()， 就不会报错了。依稀记得以前的版本也没有出现过这个问题。推测是某个地方出现了按键映射方面的问题？
P.S. 完整运行信息：
