I'm sorry not to be able to help you with this issue @davidtessier, since I haven't had such thing happening myself, but I just wanted to say I didn't find your question illegitimate or so badly asked.
It's always possible to provide more details when one has issues, but it's not always easy to know which details one can provide when one is not an expert of some software. Then when one is an expert, usually they don't need to ask questions anymore. So to me it seems quite natural that people asking question don't always ask them perfectly or forget to add details that could be useful to answer them.
In this case, I think the question explains well the issue, and you did the effort to give some info on your setup (also in the first version of your question, with the plugins screenshot) and there was even a little demo of the issue.
Additionally, it seems that after asking the question you also posted comment on a github issue relating it to this topic (and not simply duplicating the question). To me this is not wasting time of people in different places, but on the contrary, it's adding more material to the github issue, which could help people reading it to better figure out how to resolve it.
I believe asking questions is not wasting people's time. There are some other software I use which have great documentation, but in the end I've already read it all and still encounter issues. Their forum is full of people asking and answering questions, with an active community. In the end I spend more time on their forum learning about stuff than asking questions, and it's a great repository of knowledge for all the various stuff that could never fit in a documentation. So asking questions on a forum is also a way to improve the collective knowledge available for anyone online, making everyone more able to solve their problems by themselves.
Then I don't know if grav has such goal with this forum. I don't know if grav wants to create an active community. But if so, I think it's important to consider questions and people coming up to the forum not as nuisance but as active contributors. Using a software is already a contribution, asking questions is another, when one does it with courtesy, without expecting to be served, and making an effort to formulate it clearly.
It seems to me the initial question in this thread was doing this.
Sorry for the long message, I hope it's a useful contribution to this community and doesn't make anyone waste their time.
Cheers.
