If a<br />
key is not considered pressed, no key release is sent. This can happen<br />
for example if the compositor grabs a key press (global shortcut) but not<br />
the release. The Wayland client cannot do anything with the release as it<br />
never got the press. Thus it doesn't make sense to send the release.</p>
<p>Similar if a key is already pressed, it doesn't make sense to send<br />
another press event. This ensures that if the server sends in repeating<br />
key presses they are filtered out. Key repeat is handled on client side.<br />
Also if several physical keys send the same key code, pressing them at<br />
the same time won't send double press/release event.</p>
<p>This change might cause regressions in KWin in case KWin does not handle<br />
the situation correctly. But that would be a bug in KWin which needs to<br />
be fixed there. If it causes regressions the bug might have shown in<br />
other situations as well.</p>
