vinhtq115 Posted December 9, 2018 Share Posted December 9, 2018 (edited) I'm having color banding on my Dell G7. It has an Intel UHD 630 Mobile and Nvidia GTX 1060 Max-Q (already disabled by patching ACPI). I have tried all ig-platform-ids and none of them fixed it. This is how it looks like when I see it directly but when I took screenshot and open it on Windows, it had no problem at all. If you have fixed this issue before, please let me know. Thank you in advance. debug_24082.zip Edited December 10, 2018 by vinhtq115 Link to comment https://www.insanelymac.com/forum/topic/336816-color-banding-with-uhd-630-mobile-on-mojave/ Share on other sites More sharing options...

SavageAUS Posted December 9, 2018 Share Posted December 9, 2018 Well if you have read the first post for framebuffer patching you would see Laptop: 0x3EA50009 (default) And you would also see that they need to be entered in reverse byte order Laptop: 0900A53E <--- That is the value.

Alright. After that, I put -igfxdump and -igfxfbdump boot flag and restarted but now I don't know where IGPU framebuffer kext and native and patched framebuffer table were dumped.

vinhtq115 Posted December 9, 2018 Author Share Posted December 9, 2018 I don’t find anything dumped there. I will revert back then redo because since I restart, my machine keeps crashing after few minutes.

Make sure boot flags are set correctly and saved.

vinhtq115 Posted December 9, 2018 Author Share Posted December 9, 2018 (edited) Dumping worked. Here are the files. What should I do next? AppleIntelFramebuffer_10_18.2.zip table.zip Edit: I tried to follow the tutorial of Intel FB-Patcher but I still got color banding. Tested with AAPL,ig-platform-id 3EA50009 and 3E9B0000 but none of them fixed the issue.

Use ResXtreme to change to ARGB8888. Although the color banding doesn't go away completely, it's less noticeable in some cases.
