Problem:
In the steam_legacy version (build 8684), the original hw.dll hardcodes the alpha channel to 0xFF (fully opaque) during the text blur rendering. Because of this, when custom HUD with blur/dim effects are enabled, ugly black/dark rectangles appear around the text instead of a smooth translucent blur.
Solution:
Added an in-memory patch that finds this exact place and replaces the broken instructions. It sets the base color of the blur to pure white (using PUSH -1 and POP [EBX]) while correctly preserving the calculated alpha value.
Thanks to stack optimization, this fix fits perfectly into the original 10-byte space without touching or breaking any surrounding code. The patch is safely disabled for newer Anniversary builds where it's not needed.
