Intel Iris XE fails to render many things.

[sophfee]

Describe the bug

When I'm working on my laptop (All specs will be listed in additional context) I cannot do any of the following (they just won't work properly)

• Render dynamic lights.
• Preview baked or dynamic lights (Sometimes it will generate what looks like indirect light when I preview lighting in Hammer)
• Render reflections
• Compile cubemaps

To Reproduce

Have a laptop (possibly desktop too?) with Intel Iris XE Integrated graphics and run s&box.

Expected behavior

Properly render

Media/Files

Visual bugs on main menu

Preview lightmap in hammer doesn't render correctly (Was generated on desktop, specs listed in additional context.)

Preview lightmap generated on Intel Iris XE

Most of this is also the case on Adreno Snapdragon, while I don't have an Intel UHD GPU I can validate it on a Surface Duo

I know why some of these happens while others need a more in depth look

Hey, I don't have a Intel Xe graphics card at hand but these should be fixed

[samzanemesis]

This is fixed on Snapdragon

Sorry for the delay, I'll boot up s&box on my laptop and test it out.

In-game, Dynamic Lights work as intended! This map had no lightmap on my machine but handled to (with heating up my laptop and spinning the fans like all hell) render it as intended

The main menu still has this bug.

I don't have the time right now to test compiles, but I will run a compile when I am home.
