As I can't add to the initial post anymore, I continue the reports with this new topic.
For the detailed description of the bugs see Mailwasher: New artifact since wine v9.12.
The issues are still present in v10.3.
There was one version of v9.2x, either v9.21 or v9.22 where it was even worse, but all other versions since v9.12 and all v10 versions (including the latest v10.3) all have those two described artifacts.
