awt: ConfigureNotify changes in Plasma 6.2

[Vlad Zahorodnii]

Hi,

Some KWin implementation details had changed in 6.2, and, unfortunately, 
this broke awt, see 
https://bugs.java.com/bugdatabase/view_bug?bug_id=8338751 for more details.

Plasma 6.2 had been released yesterday, and we start to receive bug 
reports from our users about this issue. Is there something that we can 
do more to help resolve the issue? As a short-term fix, we may roll out 
a workaround https://invent.kde.org/plasma/kwin/-/merge_requests/6587 in 
6.2.1, which can be disabled by setting KWIN_NO_AWT_QUIRK=1 envvar for 
the testing purposes, but it's not something that's expected to work 
reliably or last long enough.

Regards,
Vlad
