@khaledhosny This is your call if this is worth fixing, it seems like a regression to me but I could be wrong.

[khaledhosny]

They are too light because they are smaller and were scaled down without optical compensation. I think the digits are too small but that is because of the existing sign design.

I wouldn’t consider it a regression, since the before was completely broken. But it is an enhancement that should be considered in the future.

Ok thanks, this is not a blocker for the v2.011 PR then, but I'm not going to close this issue so it can be considered as an enhancment in the future.
