The final HD3000 glitches removal brainstorm!

The Intel HD3000 is an old (and crappy) chip that is natively supported on macOS but many users experience some graphic glitches (weird horizontal flickering lines, garbled icons, etc).

These are the solutions I've read and tried on my system:

• Modify and inject a custom EDID via DSDT or Clover. I used one of a MacbookAir with the timings and display size of my own.
• Get 8GB of ram or more. I have 8GB and I tested 2 borrowed sticks of 8GB for a total og 16GB and still got the glitches.
• Set a custom resolution of 1360x768 instead of 1366x768. No luck.
• Use slide=0 as a boot argument. I've even calculated my correct slide value (on Clover's forum) and my slide=39 doesn't allow me to boot.
• Use an alternative memory driver for Clover UEFI. I've switched from OsxAptioFixDrv, to OsxAptioFixDrv2 and 3. Even AptioMemoryFix.
• Do an EC reset (remove battery and press power for 30 seconds). No luck either.

The point of this thread is to exchange ideas on how we can get rid permanently of those glitches.

It's very annoying that I can use the laptop for a long time without glitches and sometimes like a minute after I turn it on, the glitches appear.

My specs: Asus U46E, Core i5 2430M, Atheros 9385, ALC269, 256GB SSD. High Sierra 10.13.3. Clover r4394.
