layers with same name will make system slow to an unusable level

If I mistakenly add 2 layers to the layer panel e.g. each named "IPT_SouthShore_unique", system slows to a crawl. Each layer points to the same shapefile. When I remove one of the layers, system runs fast again.

Id there is no underlying bug e.g. natural contention is occurring, then an enhancement to add new layer could check for existence of layer with same name, possibly warn user and give option to proceed or not.

Can't confirm this on 3.6 and both Linux/Windows. Could you attach a sample shapefile that shows this problem? have you tried with a new/clean profile?

Upgraded to new system with a clean install of 3.6. This symptom has disappeared at the moment so we can close this off. Thx for the assistance.
