Same use GDIPlus.dll, Same Source Code..
Why is the result different?
Sawtooth is serious. This should not be related to Lazarus.
But there are problems.
- no code to reproduce
- not even delphi and lazarus/fpc versions ?
- did you try to enable hidpi in Lazarus (search on the forum to see where)
So there is not much to work on. Next time a bit more info please.
Anyway, depending on the Delphi version it could be the manifest. The manifest parametrizes GDI (and I assume gdiplus too), as well as the cleartext font engine. The hidpi bit above is related to this too, but afaik preprepared in lazarus (maybe only trunk) ?
