SetLog(z) causing wrong color-coding?

ROOT
1

Hey,

I have a regular TH2D filled with some data and draw it in 2D mode (“COLZ”).
When applying
canvas->SetLogz(1);
the color-coding gets complet wrong compared to the histogram with normal color-coded Z-Axis.
One additional information: the integral over all y-bins for constant x bin is 1 per construction.
I attach two example plots, one with SetLogz(0) and one with SetLogz(1).
I’m running root 5.28.00 on MacOS 10.5.8.
I have also tested the code on a linux machine with root 5.26.00, there this error is not present.

So is this a bug in the new version or is my code?

Thanks,

Stephan

There’s bug in 5.28.00, already fixed to my knowledge.
