Using linux and reinstalled Gimp ? Unless it is an upgrade that should not be necessary. Typically there are a multiple dependencies that will remain. Then Gimp 3.0.6 - is that correct or a typo.
However, A reset gets it working for a short time, so you need to ask yourself, was working, not working now, what happened in between. Are you working in a high precision ? Is more than a single layer selected ?
You could try posting a screenshot of the whole Gimp interface just as that weird effect takes place. Showing tool options and layers.
