Bug ID: 58640
           Summary: winewayland unconditionally sends RCtrl when pressing
                    RAlt
           Product: Wine
           Version: 10.13
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: winewayland
          Assignee: wine-bugs@winehq.org
          Reporter: miles@milessimpson.com
      Distribution: ---
In dlls/winewayland.drv/wayland_keyboard.c, at line 831 (as of 10.13 sources),
there is an unconditional Right Control forced when pressing the Right Alt key,
regardless of keyboard layout, shown here:
/* NOTE: Windows normally sends VK_CONTROL + VK_MENU only if the layout has
KLLF_ALTGR */
if (key == KEY_RIGHTALT) send_right_control(hwnd, state);
This interferes with "us" keyboard layouts and programs that treat left and
right alt keys independently. This differs from XWayland where a R_ALT keypress
is sent through unmodified for the "us" layout.
The line in question has a comment mentioning that this should only happen when
KLLF_ALTGR is specified. There are layouts with that specified, but this check
does not factor that in when deciding to send R_CTRL.
