Also, it seems that you CAN re-enable Unified Strength after you’ve whacked up the fill strength to 100% (whilst Unified Strength is disabled).
It looks like the bug – and it clearly is a bug – is that when Unified Strength is enabled, the fill strength is locked at whatever value it was at when Unified Strength was ticked (regardless of what you adjust the strength value to).
So, in effect, what we were seeing is the fill tool locked to 50% strength under the hood, but it was *saying* 100%.
