php warning rename and filesize

[sissibieber]

hello, it seems that sometimes when converting an image with (WebPConvert::convert($new_dir, $new_dir.'.webp', static::$webpOptions);) I get the following php warning in my error_log. Not sure if this is a timing issue (so lossy and lossless images are created too slow and the function for comparing both (convertTwoAndSelectSmallest()) is called before they are there or if really one is missing?
