What's Wrong?

When I use the Claude windows client, sometimes alt-tab stops working. This problem seems to be fairly consistent once it starts: windows/tab or alt tab dont work, closing and reopening the client doesnt work either. Bug seems to happen both in screenless and windowed modii. When working in split-screen and alt tabbing from the other program to something full-screen, only that side of the screen gets replaced.What does work is minimizing the client.

What Should Happen?

alt tab should work as intended
