I am trying set up gSender 1.0.4 on a Pi4 with Rasbpian 10 Buster, and when I run the app it appears scrambled. I can click buttons but it’s unusable. I’ve tried a few different screen resolutions and it is currently set to higher then the required (1920x1080)
We actually didn’t end up releasing a 1.0.4 Pi version due to build issues, so my assumption is you might be running a version for a different architecture which could result in the issue you’re seeing.
1.0.5 does have a specific Pi version - look for the arm7l versions, either .deb, .appImage or .rpm.
Let me know if that fixes your issue - if not we’ll continue to trouble shoot.
