Hi,
is there any way to force the size of a sprite to be rounded after scaling? I didn't find anything except a "setSize" that existed in previous SFML versions...

It's very strange that this function doesn't exist indeed.
The workaround is to use sf::RectangleShape, I guess.

I wonder why it was removed.

Because setSize is really just setScale(size / textureRect.size).

Yeah, but you can get a ton of rounding errors because of division/multiplication.

If so, setSize did not solve anything

Ah, I remembered how Transformable stores scale and later computes transform matrix.
Yeah, in this case getting rounding errors is inevitable.

OP should probably use RectangleShape for precise integer sprite sizes, yeah.
