Description Dirk Fauth CLA 2023-03-29 03:44:16 EDT 
If in frozen state dynamic scaling can cause a rendering glitch in some scenarios. For example if there are columns in the frozen region with a width that causes rounding issues (e.g. 83 downscaled) it happens that the non-frozen region is not rendered anymore.

It looks like the issue is the calculation of the minimum origin. The recalculation of the minimum origin is done based on the current value. But because of the rounding issues the resulting value is not the same as calculating it newly from the minimum origin column value that is stored.
