windows-10-update-kb4093112

​ If you look at the "Known Issues in This Update" section above, you may notice an unexpected movement or scrolling behavior while using the pen after applying the update. Therefore, please try the following method to check whether the problem is solved.

​ 1. Search cmd at startup.
2. In the search results, right-click Command Prompt and select Run as administrator.
3. Copy and paste the following command at the command prompt that you issued.
reg add HKEY_CURRENT_USER Software Microsoft Windows CurrentVersion Pen / v LegacyPenInteractionModel / t REG_DWORD / d 1 / f
4. Press the Enter key.
5. After rebooting the PC, connect EasyCanvas to check if the pen input works normally.

The pen pressure input of Apple Pencil does not work in Photoshop or Clip Studio.

Currently, there are two types of pen input methods that can be used in Windows: the Windows standard
input method and the "Wintab" input method supported by Wacom.
EasyCanvas application recognizes pen input using Windows standard input method.
Therefore, if the drawing tool such as Photoshop or Clip Studio is set to use Wintab, the pen input can not
be recognized or malfunction can occur.
Below is a description of how to change the input method in Photoshop and Clip Studio.

1. Photoshop

　　1) If there is a running Photoshop program, it will quit completely.
　　2) In Windows Explorer, go to"C:/Users/%USERNAME%/AppData/Roaming/Adobe/Adobe Photoshop CC 20XX(version to use)/Adobe Photoshop CC 20XX Settings/Adobe Photoshop CC 20XX Settings"
　　3) If there is a PSUserConfig.txt file, open the file and change the contents of UseSystemStylus 0 to UseSystemStylus 1.

2. Clip Studio

　　1) Run Clip Studio.
　　2) Select "File" - "Preferences" on the upper tab.
　　3) Move to the tablet tab, select "Tablet PC" in the "Tablet service to use" column and save it.



Also, if you are using a brush that does not support writing pressure in Photoshop,
the writing pressure may not be applied.
To check the brush that supports writing pressure, you can open the brush preset window
(press the F5 key, open the brush window and click on the brush preset button.) During brushing,
Brushes whose thickness and hardness do not change in the entire line do not support writing pressure.

In other words, the brush in the red block in the image above is a brush whose writing pressure is not supported.

Display Scaling Setting

EasyCanvas uses virtual hid device (touch, pen) and it is mapped to the display device with 1:1 mapping.
Since touch(stylus) input is calculated based on current display's scaling method, in order to use it properly,
we need to set the same scaling mode in tray menu as specified in the gpu's display settings.

[Intel Display]

Use Intel HD Graphics Control Panel (General Settings > Select Display > Scaling)

Mode
Maintain aspect ratio
Full Panel
Center

[AMD Radeon Settings]

Use Radeon Settings (Display > Select Display > Set Scaling Mode)

Mode
Maintain aspect ratio
Full Panel
Center

[NVidia Control Panel]

Use NVIDIA Control Panel (Display > Adjust desktop size and position > Select Display > Select a scaling mode)

Mode
Aspect Ratio
Full-screen
No scaling

[EasyCanvas]

Mode
Scale Full Screen
Maintain Aspect Ratio
Center Image

If you select the mode that matches the display setting, you can input normally.

Input error about temporary extended display

Temporarily expanded virtual displays that do not have actual monitors may not support a pen or touch input.
In order to receive a pen or touch input on each display, it must be the display of an actual monitor.

Adjust display color

EasyCanvas does not support a color adjustment function.
If you need to display a color-adjusted screen on your iPad, please change it directly on your iPad.

Display margin

Screen margins occur because the resolution ratio of the mirroring screen does not match the ratio of the mobile device, and can be resolved by changing the resolution to match the mobile device.
However, if you set the resolution on your mobile device, you may experience margins on the PC screen.

Display delay

To improve the display output performance, try lowering the display resolution you are currently using on your mobile device.

Network connection

Yes. The EasyCanvas app is available through a regular subscription system, so it needs to run in an Internet-connected environment.

Not input Stylus

When using the Wacom pen, the left and right edge of the iPad will not recognized the pen input.
This is the own behavior of the Wacom Bluetooth Stylus itself, which is the same for other app that support the stylus.
