Rendering problems with shaders on Intel integrated graphics - Almost unplayable

[Inderix]

To get straight to the point, this is how it looks with Sildurs Vibrant Shaders:

As I mentioned, I'm playing with integrated graphics (we'll ignore the fact I'm running shaders on an iGPU), if that is helpful to what could be happening.

As for mods I'm running in this installation:

• BetterFPS
• Born In A Barn
• FastFurnace
• FastWorkbench
• Optifine
• Particle Culling
• Performant
• Phosphor
• VanillaFix

My system specs/info, if that's also needed:
Intel Celeron N4020, 2 Cores, 2.8GHz
4GBs Memory
Linux kernel 5.10.106, Ubuntu 22.04 LTS, KDE Plasma 5.24.4
Mesa graphics driver
(Small note, my laptop is a Chromebook that has had it's OS replaced, and while I decided to not change it's firmware, I am however forced to using a version of the ChromeOS kernel - Hardware and most software is nearly identical to those found in non-Chromebooks so this shouldn't be a possible issue)

I'm willing to provide extra info if needed, although I've probably already gone overboard on the info.

Shaders barely work at all with fp2 currently
There are a couple that look ok however

You could try Sildur's Light. It was tested and should work a little better.
