LiveCode Builder is a language for extending LiveCode's capabilities, creating new object types as Widgets, and libraries that access lower-level APIs in OSes, applications, and DLLs.

From the screenshot, it looks like the rect of widget is smaller than it should be, so the text is cropped. Try clicking on the rect on Edit mode and then resize it.

PS: Hermann has created a pretty rotatingText widget
This is a bug of LCB (linux only), the "orientedText"-widget does also not work correctly on linux.
#20446 (at least related to that bug as it shows the same effect).
In this case the main criterion for not fixing in 8 was (lack of) ease of backporting- unfortunately it would have been a different fix due to the graphics library changes in 9. Also in this case proximity to 9 GM was a factor.
