[Bug]: The screen glitches when waking from sleep mode.(IntelMac)

### Kernel

6.19.10-1-cachyos /7.0.0-rc5-2-cachyos-rc /6.18.20-1-cachyos-lts

### Desktop Environment / Window Manager

KDE Plasma

### CPU

2nd Gen Intel(R) Core(TM)i5-2500S/(iMac 2011mid/21.5inch LCD(A1311))

### GPU / Driver

Device-1: Intel 2nd Generation Core Processor Family Integrated Graphics driver: i915 Device-2: Advanced Micro Devices Radeon HD 6750M driver: radeon :v

### Description

When the computer enters sleep mode and then resumes, the screen becomes corrupted and does not display correctly.

However, this doesn't happen every time; it resumes normally once in a while.

When the screen becomes corrupted, pressing Control(CTRL)-Option(ALT)-fn-F3, Control(CTRL)-Option(ALT)-fn-F1, and then Control(CTRL)-Option(ALT)-fn-F2 to switch virtual consoles restores the display to normal.

### Steps to Reproduce

1.I'm setting up a dual-boot iMac 2011mid with macOS, installing rEFInd on sda3 and the CachyOS main system on sda4.

### Expected Behavior

A normal login screen that is not corrupted.

### Actual Behavior

This is just a guess, but it's likely that the computer uses the integrated Intel graphics when the load is light, and switches to the Radeon graphics when the load increases. The screen corruption may be due to a failure in this switching process.

### Additional Context

Currently, this issue has only been confirmed with the A1311 model, but it may also occur with the A1312 (27-inch type) from the same period. Furthermore, it may also occur with later iMacs with similar hardware configurations.
