I am using version 2021061600.
The game runs fine in Valkyrie mode.
There is one problem. Subscreen cannot be activated. It is not possible to activate Subscreen in windowed mode or full screen.
If I assign a button to the Toggle Subscreen in spicecfg and press it, it doesn't respond, and even if I enable Force touch emulation in the option tab, I can't see the subscreen.
My operating environment is a FHD resolution laptop equipped with a 144hz panel and a 27 inch 144hz monitor with FHD resolution, and the 27 inch monitor is designated as the main monitor.
Since the frame limit in the game is set to 120hz, it is neither fast nor slow, and the game runs normally on the main screen.
I would like to know how to solve the problem.
