Spark is notorious for opening up half way cut off when you log in or hidden off screen. There are a lot of tricks out there for moving it around with the mouse or arrow keys but digging through the Spark directory in the AppData\Roaming folder I’ve found a few config files that can be edited to quickly solve this problem for users.
This is for the Windows version but you could probably adapt the process to Linux or Mac, since I assume it uses similar, if not identical files. You’d just need to figure out where they are stored.
How to Fix Spark Main Window Showing Up Off Screen
Step 1: Close Spark completely. Either right click the flame icon near the clock, or kill the process in Task Manager.
Step 2: Navigate to the following folder.
You can also just click your start menu button and type %USERPROFILE%\AppData\Roaming\Spark
Step 3: Open the “layout.SETTINGS” file in Notepad
Step 4: The file will have the following text or something very similar.

Change the numbers in the lines “mainWindowY=1120” and “mainWindow=500” (they are in bold) to:
Note you can just copy and paste the two lines above to replace the two lines in your SETTINGS file.
Step 5: Save the layout.settings file.
Step 6: Open Spark and log in and see if it doesn’t center the main window on your screen. If it doesn’t, you didn’t have the Spark.exe process entirely killed when you edited the file.
You might be able to just delete this file entirely and Spark will rebuild it with defaults, I haven’t tried, but I suspect it might.
