Texture Problems Since the Last Valve Update

[teddthebucfan]

Since the last big Valve update, the one that caused the client.dll error, I've been having trouble with several maps and props:
1. HL2 Textures show up in TF2 maps, as seen below:

And I have tried the map texture pack from garrysmod.org twice now.

2. Even worse is that black patches appear everywhere.

3. Occasionally, along with black patches, all maps loaded will be fullbright.

If you know a fix for any of these problems, please help.

As stated, set to shader high. The HL2-TF2 texture problem is because of the Half-Life files are using the same name some textures that TF2 uses, and of course, Half-Life 2 will be forced on.
