BUG: 'Static' effect on textures. Drivers? How to fix?

[Apex]

Hello. I am having yet another texture/material related issue. I haven't been able to find this anywhere else on Steam or otherwise on the internet, so I've started a new discussion for this issue. Here is my problem:
_____________________________________________________________

Valve recently pushed a patch that fixed the bright and shiny rock textures in the underground sections of the game. However, since that fix, I have experienced a new issue: buggy static-like effects on many of the floor-tile textures throughout the game. The effect in the screenshot below sort of 'jumps' to a new location and/or scale every frame, creating an effect that looks very similar to the 'no-signal static' effect on old CRT televisions. Needless to say, it's extremely distracting, and quite annoying.

I've tried lowering all settings, raising all settings, and using the command "mat_reloadallmaterials". I've also tried setting mat_specular 0" with no change to this effect.

If anyone has any ideas, please let me know. I'm working on creating a short gif of this effect, will link soon. Thanks for any and all help.

portal2_dlc3 is the culprit for this glitch. As discussed above, whatever fix they made for the underground rock textures happened to also cause this static effect. Rename or delete the portal2_dlc3 folder to revert this patch.
I recommend doing this, because the static glitch is way more common than the glowing rock glitch!

Actually, playing through chapters 1-4 now, I have only noticed one instance of the static effect glitch, (and its actually more subdued now) it occurs on the white panel sitting on the floor of the first laser test of 'The Cold Boot'. (The surface the laser is pointing down at). I havent noticed it anywhere else, so i feel driver updates have partially fixed the issue. (At least for me. Ill continue testing the game)

Also, the glowing rock glitch is far more annoying in my opinion.

Just edited my post, turns out I was completely wrong. On the bright side, we know that dynamic lighting is the specific cause of this glitch,

Really? Thats odd... Because I never saw any static effect on the dynamic shadows of spinning fans. (Is that different from dynamic lights?)

I don't think dynamic light in its entirety is causing the glitch. However, with lighting disabled entirely, the glitch never occurs, likely because whatever the cause is IN the dynamic lighting is getting disabled also.

Disabling lighting also disables reflections, shadows (which aren't real shadows in most cases, they're projected textures), ambient and baked (static "pre-rendered" lighting), and even depth mapping, from the looks of everything. (i'm not 100% positive about that last one. I haven't found any documentation saying it's tied to the lighting, but the "wavy" effect no longer appears on shiny black panels and the tiles and panels no longer have visible gaps between them.) My point is that it could be any number of these things and the glitch stops occuring when the glitchy thing gets disabled.

I do not know the console commands well enough to disable these things individually, and they can't be disabled through the in-game options menu because they're all tied together under 'lighting' or 'effect quality' or one of those options. I'll try to figure out how to do this, but can anyone help in that regard? I'll try to see if I can somehow do this via the nvidia control panel as well. This may not be possible if the systems are all tied together in Source Engine. (eg if the depth mapping works differently than other games.)

Driver updates seem to have repaired the issue for the most part though. I only have one recorded instance of the effect now, and even then the effect is less intense than it was before.

Thanks for the information, but unfortunately, driver updates haven't solved the issue for everybody.

Update: I now have 3 recorded instances of the static effect. 1 is in the first test of 'The Cold Boot', and the other 2 are during 'The Itch' and 'The Part Where He Kills You' (I think they were in seperate chapters. I know for sure one was in a test chamber during 'The Itch', but I cant remember if the last one was during 'The Itch' or 'The Part Where He Kills You'.)

Yet another Portal 2 update, but no information on it at all this time. Must be another automated steam thingy.

Valve please fix this ;-;

[Framed Kitty]

no, this update was to fix something else - https://steamcommunity.com/app/620/discussions/0/1694922980049026824/#c1726450077625874228

this update fix this white particle bug ?

or not ?

Ive been having this for awhile and noticed it a long time ago. This is the only source game that this happens on and yes I do have an NVidea (so its an Nvidea thing) cause my friend with an intel doesnt have this problem. (If it adds to anything, with an nvidea card you cant have smooth shadows in Garry's mod cause Nvidea released and updated that messed with Source's smooth lighting or something like that.)

this useless steam support does not do anything to fix it, I already contacted them 30 thousand times and they did nothing.

Intel and Nvidia are seperate processors. Intel are CPU and Nvidia makes GPUs. Although we do believe it to be a Nvidia issue, other have claimed it occurs on AMD rendering devices as well.
