* On macOS Big Sur (and possibly other OS versions) when connecting a DualShock 4 controller either via Bluetooth or using a USB cable, two separate controller devices are registered in parallel. This is a bug in either macOS or the DualShock driver and it makes it seem as if ES-DE is registering double button presses when actually two separate controller devices are generating identical input. A workaround if using Bluetooth mode is to plug in the USB cable just after connecting the controller, wait a second or two and then remove the cable again. This will remove the cabled device, leaving only the Bluetooth device active. Another workaround is to enable the setting "Only accept input from first controller" in the ES-DE input device settings. The reason why this bug may not be visible in some other games and applications is that ES-DE enables and auto-configures all connected controllers. * On macOS Big Sur (and possibly other OS versions) when connecting a DualShock 4 controller either via Bluetooth or using a USB cable, two separate controller devices are registered in parallel.

* Some screen tearing can be seen in the upper part of the screen when using the slide transitions with certain graphics drivers and resolutions. This problem will hopefully be resolved in ES-DE v1.2 when moving to the GLM library.
* On Windows when using high DPI displays, if not running ES-DE on the primary monitor and the display where it runs does not have the same scaling percentage as the primary monitor, then the ES-DE resolution will not be properly set. The application will still work and if running in fullscreen mode it may not even be noticeable. This issue is caused by a bug in SDL where the primary display scaling is always used for calculating the display bounds and as such it needs to be fixed in that library. If using the same scaling percentage across all monitors, or if not using high DPI monitors at all, then this issue will not occur. * On Windows when using high DPI displays, if not running ES-DE on the primary monitor and the display where it runs does not have the same scaling percentage as the primary monitor, then the ES-DE resolution will not be properly set.

ES-DE fully supports high resolution displays such as 4K, 6K, 1440p, ultrawide monitors etc. But some emulators such as RetroArch will also run using the same resolution which may cause performance problems on slower machines or when using resource intensive shaders. Although some emulator cores will have options to set their internal resolution, they still need to be scaled up to the screen resolution. On Unix it's possible to start ES-DE with the `--resolution` option to set a lower screen resolution (this will also affect the emulators) but this is not really recommended as it's highly dependent on well-written graphics drivers for proper behavior.
