Attached is my suggested fix for the keyboard bug. The
behavior should be the same as before, except when losing
the focus (FocusOut, LeaveNotify) all keys are released
(normal keys first, modifiers at last), and on re-entering
(KeymapNotify) pressed (modifiers first, other keys afterwards).
I'll
There's a problem with the keyboard support on X11. It's really
caused by the way X works, and SDL or glut are said to struggle
with it as well. I haven't seen the problem there, though, so
they probably found a way to work around it.

Hello Franz,

keys (let's say Ctrl and Shift) and while keeping them pressed
switch the desktop (e.g. on KDE) or minimize the window. Release
the modifier keys. Now, when you switch back or open the minimized
window, you'll see

And again: I never saw that

On the Windows side, we could explicitly poll a modifier key's state
before sending an event off to the EventQueue, without relying on
KEYUP/KEYDOWN synchronization. However, doing something like that
would cause inconsistencies between the

X11 does, of course, tell you which modifiers are active. But only
which modifier level (shift), not which modifier key (shift_l, shift_r),
so you'd still release keys that were never pressed before. (I'm not
sure if that's really a problem, but it
