That is just the way it is using composite (RCA). Composite has a fixed resolution which is less than the VGA resolutions that many applications expect. This makes many programs unusable on the RPi in composite mode.
If your screen supports PAL then you might try that as PAL has a little bit better resolution than NTSC. Many of the more recent small LCD screens support both but the RPi defaults to NTSC.
Unless specified otherwise my response is based on the latest and fully updated RPiOS Buster w/ Desktop OS.
