Alt-Tab while cursor on canvas causes cursor to get stuck

Switching windows through alt-tab while the cursor is on the canvas causes the cursor to get stuck on the canvas. Any click or keyboard shortcut doesn't work while this happens. The only workaround is to move the mouse out of the canvas.
This doesn't happen when you switch through another window through minimizing.

Why does this affect me: because my workflow includes switching to another window with references through alt-tab.

Steps:

1. Open Pixelorama
2. Open a new document
3. Move the mouse cursor inside the canvas
4. Switch to another window through alt-tab
5. Switch back to the Pixelorama window through alt-tab
