Ok, i can confirm that in new version there is no problem with x264&Xvid tabs appearance on my system as well.
Hybrid_no_button_text, i got it, but hope it is not a permanent change? Plain icons images still look rather small and less comfortable to locate and press compare to basic buttons with text.
UI have a lot of free space to fit wider buttons, so tiny icons will not help to save space.
Some icons consists of two elements and determined by the eye as two separate buttons. But it is a different story, it is always possible to redraw them somehow...
How many buttons are you see here? 7 or 8? Where to press?
Seems only 5 buttons here and a lot of area to hover mouse button and press it:
In Hybrid there is large and nuanced system of actions and in many places multiple icons arrays are rather confusing and hard to understand. Same time text descriptions for buttons are perfectly written. (I only noticed "Save/Save Same" aka "Save As.../Save" confusion, but both variations works well and don't produce any confusion in understanding)
Icons works well for basic well defined actions. Or when icon defined some tool (like tools in graphic/3d/cad and apps) For example PayPal donate icon/image in main tab looks nice and easy to understand...
