The author recently explained that he sadly does not have the time or energy to look to fix the issues for the foreseeable future - and unfortunately a small number of the (GTA) community has been quite abusive in response with just discourages authors to try to fix such issues, but as Cyan points out it is open source and there are others looking at the code to see if they can apply a fix to the issues.
So hopefully (I am hoping) there will be a possible fix or workaround soon.
