All FNC component are very interesting and contains a lot of good idea. But some have performance problem like TMSFNCRichEditor.
Open TMSFNCRichEditor Demo compile and start it.
- Try sample Sample "Format".
=> Try Resize with with mouse, it's slow and crash (now answer and high CPU) after a certain time if you reduce it !
- Sample "Many lines"
=> Try to reduce a lot the width => TMSFNCRichEditor disappear !
- Sample "File test"
=> Try to change size it is very slow ( compared to native TrichEdit component) even on a high-end CPU (Core i7-12700K) with quick graphic card.
Same problem on version VCL and FMX debug or release on Delphi 11.
