[Bug 33056] Tablet stylus pressure works in Manga Studio 5 until a focus or key event occurs

--- Comment #6 from Kanzaki Wataru  ---
This bug manifests itself similarly in Clip Studio Paint EX 1.6.2 (same
software as Manga Studio, different name) using Wine-staging 2.2 on Ubuntu
16.04. The tablet is an Intuos 3. The pressure works if the pen is hovering
above while the application is starting up, and continues to work until it's
lifted up. After that it will not draw anything (no pressure).
