Thanks a lot, @Gigasoft and @Octocontrabass! I write PLANE_SURF at last now but still get the corrupted plane 1.
My new commands are:
```
sudo intel_reg write 0x70290 0x0137027f; \
sudo intel_reg write 0x7028c 0x03ff02ff; \
sudo intel_reg write 0x70288 0x28; \
sudo intel_reg write 0x70280 0xc4842000; \
sudo intel_reg write 0x7029c 0x02180000;
```
The display is:

PS: Are there any programs/libs utilizing the plane 2 as an overlay?
