Small gap on screen when maximized, cannot drag past, full-screen okay

There is a gap between the right side of a maximized window and the edge of the monitor (aka opposite my task bar). This frequently happens after I exit a full-screen Steam game (such as cs:go), but I don't know if it's because of the game/video drivers, or if Cortex starts whatever problem causing application to open up again incorrectly. Restarting Explorer does nothing.

This has been asked and answered a few different times, but I was hoping there was a way I could dump my currently open tasks, or startup tasks, and have it narrowed down versus restarting my computer 400 times.

This is what Razer Cortex closes then starts back up when I leave a game:
Processes:

• amddvr.exe
• amdow.exe
• jetbrains-toolbox.exe
• RadeonSettings.exe
• RescueTime.exe
• SearchUI.exe
• ShareX.exe
• SkypeHost.exe
• UninstallMonitor.exe

Services:

• DPS
• fdPHost
• FDResPub
• FontCache
• PcaSvc
• QWAVE
• Spooler
• stisvc
• StorSvc
• TabletInputService
• TermService
• VaultSvc
• W32Time

Non-Windows Services:

• AdvancedSystemCareService11
• IObitUnSvr
• KMWDSERVICE
• MBAMService
• TinyWall

Today I had the problem, locked my computer, and was away from it for 4+ hours, and no longer have the problem. No clue if that narrows it down.
