Reason 13 Preferences Blank Areas

ReasonStudio's DAW Reason is showing a lot blank areas in its preferences
window (which looks like a standard win32 window). This makes understanding and
interacting with the options of Reason impossible.

How to reproduce:
1. Follow download and installation instructions from here:
2. (if not authorized) click on "run in demo mode"
3. Finish initial configuration wizard
4. Press Alt+Arrow Down to open the main menu, press Arrow Right followed by
Arrow Up to select Edit->Preferences via your keyboard
5. Preferences window opens with blank areas (bug) but behind main app (that's
another wine bug) so change focus to the window that just opened behind Reason
6. Note how "0134:fixme:uxtheme:DrawThemeTextEx unsupported flags 0x00002000"
is being logged multiple times during step 5

The attached zip file contains a screenshot of the preferences window on Wine
(tested with v9.21 and v10.0-rc5, broken from v10.0-rc6 on due
https://bugs.winehq.org/show_bug.cgi?id=10845#c29) and on Windows 10 as well as
the log when opening the preferences window.
