Final Checklist

• I have searched the issues and haven't found a similar issue.
• I have read the known incompatibilities and this is not related to one of those.
• I have installed Fugue and it does not fix this issue.
• I am using experimental branch and have installed Scalar and it does not fix this issue.
• I am running a test build from Cleanroom Github Actions. (Or, if I've compiled it myself I plan to fix the issue)
