Edit with solution:
Vegas Pro 14 build 211 fixes the broken titles and text interface.
And to avoid blurry buttons, simply set the display scaling to 149% or lower. There is still no solution for people with very high DPI displays that need more than 149% scaling.

Original issue:
Vegas Pro 14 scales buttons according to the DPI setting of the Windows display. That's a good thing if you have a very high DPI display, because otherwise the buttons would be tiny. But the scaling makes the button icons blurry. See the attached image. (you might need to download the image and view it outside your browser to see it at 100% scaling)
I use Windows 7 and my display setting is 150%. Making the buttons 50% bigger isn't really an issue either way, but I really dislike having all of those blurry buttons on my screen. Vegas Pro 13 was much better in this respect. Vegas 14 really needs an update with high resolution button icons, so they won't be blurry.
The Titles and Text interface is cut off when using a high DPI display. This bug is unchanged from VP13. This is one of the bugs that I really hoped VP14 would fix. See the attached image.
