I’ve had reports that can clear up any flickering. If it doesn’t, another option is to open the “Graphics” section of “Settings”:Ĭhoose to add a “Desktop app”, then “Browse” and select the John’s Background Switcher app (from wherever you installed it) and click the “Options” button.Īnd choose “High Performance” then “Save”, then quit and restart JBS. If right-click on your desktop and choose “Personalise”, then go to the “Colours” section and uncheck “Automatically pick an accent colour from my background” the problem may go away. This should force Windows to get back in sync again and hopefully allow JBS to switch properly Why does the screen flicker or my cursor jump around whenever JBS changes the background? Go to the standard Windows display preferences, select your non-primary monitor(s) and click ‘Identify’, return to your primary monitor and if there’s an ‘Apply’ button now enabled, click it. The latter handles monitors being added and removed and JBS not detecting them.įinally, Windows may simply be lying to JBS about the number and orientation of multiple monitors attached. In the ‘Advanced’ section of ‘More Settings’ there are ‘Work around multiple monitors being shown in the wrong order’ and ‘Constantly check for monitor count changes’ – the former does what you think it does so try enabling it, then switching JBS, or disabling it and switching to see what happens. There are a couple of options in JBS to handle wallpapers being cut off of shown in the wrong order on multiple monitors you can try. If it does you won’t be the first! □ Why are my multiple monitor wallpapers cut off or not laid out correctly? If you’re running an ASOS laptop then have a look for a process called ‘AsusOLEDShifter.exe’ – if you see it, kill it and see if that helps. You can figure out what application is locking the file by installing Process Explorer and once installed doing a search for ‘ActiveBackground.jpg’ to see what application is holding a lock on it. If you try to delete it and you’re prevented from doing so by Windows, that’s the problem (JBS can’t either and the lower level image handling code throws the GDI+ error). If you click ‘Open Folder’ on the ‘Import / Export’ section of ‘More Settings’ you’ll see a file called ‘ActiveBackground.jpg’. If that doesn’t resolve your problem it’s most likely another application that is locking the wallpaper image JBS has created. The simplest fix is to go to your PCs settings and in the ‘Account’ section look for ‘Sync your settings’ and set ‘Theme’ to ‘Off’. Since this process often locks the wallpaper JBS is trying to change it means JBS is stuck and the GDI+ error comes up. Sometimes you’ll see this error when switching if you have Windows configured to sync your theme between PCs. Why do I see “Failed to switch the background: A generic error occurred in GDI+” on Windows 10? You’ll then eventually end up on the SmartScreen dialog above.įortunately the new certificate will last 3 years so this problem will go away for that period of time! Does John’s Background Switcher run on Windows 11? If you’re running Microsoft Edge you’ll be presented with information that JBS is uncommonly downloaded (it’s not, it just means the new certificate isn’t trusted yet) so you’ll have to tell it you want to keep it (Microsoft really want me to spend triple the amount to buy an EV certificate): You just need to click “More Info” and then “Run Anyway” to get the installer to launch. Firstly it’s nothing to worry about and secondly you’ll usually see an error dialog like this one: I’ve bought a new digital certificate for code signing JBS and until enough people run it Windows Defender SmartScreen will continue to complain about it (I could pay for an Extended Validation certificate but they’re ridiculously overpriced and JBS is freeware after all). Why does Windows Defender SmartScreen stop me from installing JBS? I see JBS no longer works on Windows XP, do you have an older version I can install?.Can I tie a specific picture mode or photo set to a specific monitor?.Why doesn’t JBS support every RSS feed on the internet?.Can JBS loop sequentially through my pictures in a specific order?.Why do I keep seeing the same pictures again and again?.Why doesn’t JBS support Google or Bing Image Search any more?.Do I need to uninstall JBS before installing a new version?.Why does the focus jump from one app when the background switches?.Why does the screen flicker or my cursor jump around whenever JBS changes the background?.Why are my multiple monitor wallpapers cut off or not laid out correctly?.Why do I see “Failed to switch the background: A generic error occurred in GDI+” on Windows 10?.Does John’s Background Switcher work on Windows 11?.Why does Windows Defender SmartScreen stop me from installing JBS?.Here are the most commonly asked questions about John’s Background Switcher for Windows.
