--- Comment #1 from Gabriel Ivăncescu gabrielopcode@gmail.com --- This seems like one of those issues where the cursor messes it up. We already had problems with this in the past, so now we move the cursor to the top-left of the main window.
Which should work, in theory. In practice, I just ran these tests right now and my cursor was not moved! Because the window spawns at (0,0), and it seems SetCursorPos(0, 0) is a no-op? If I make it move to (1,1) in such case, it works...
I can't say with certainty that this is the issue, though. But if I move the mouse over the autocomplete popup, I get very similar errors. I can't reproduce it otherwise.
I guess I'll send a MR with SetCursorPos change and see what happens.
