Why killed? You can still set the DoubleBuffered property to True.
In 1.8 the DoubleBuffered property was ignored on Windows for all
controls. Instead DoubleBuffered=True was forced without the chance to
disable it. I.e. the property was absolutely useless since it is not
used on Linux/OSX either.
I just disabled the forced DoubleBuffered=True - the same what Delphi
does. The only thing LCL misses is ParentDoubleBuffered that makes
If you don't like the Delphi way but like the Lazarus 1.8 way - it's a
valid scenario as well, but then the DoubleBuffered property should be
deprecated/removed and DoubleBuffered should be handled automatically
with protected methods to override the default behavior.
