[LDPE] 0.8.50 Beta Released (bugfix / usability)

[N. W. Perry]

I have an issue that was also present in my previous version (also 0.8.50); I don't know if it's related to anything I've reported previously. When expanding the text editor into view, some buttons are missing until I mouse over them. I'll let the image speak for itself (click to view animated GIF):
   

This issue persists when using OpenGL 3.3 as well.
