Y-Scaling issue with XP-Pen Artist 22R Pro as second display
GIMP version: 2.10.18
Operating System: Windows 10
Package: Installer from gimp.org
Y-scaling of cursor is incorrect when using Gimp 2.10.18 and XP-Pen Artist 22R Pro.
PC has two displays. Primary display is set to 3840x2160, scale and layout set to 150%. Second display is XP-Pen Artist 22R Pro set to 1920x1080, scale and layout set to 100%. Displays are set to extended with Primary display set as main display. Using Gimp 2.10.18, and XP-Pen Artist 22R Pro driver v1.6.4 (latest version).
When using Gimp 2.10.18 on the XP-Pen display, the X coordinate of the brush matches the stylus position. The Y coordinate of the brush is positioned approx. 66% of the actual stylus Y position. Gimp settings for stylus are set for screen. In other applications such as Photoshop and Clip Studio Paint, the brush matches the actual X/Y position of the stylus correctly. Gimp seems to be having a problem with correctly scaling the Y position.
If the scale and layout of the Primary display is set to 100% (instead of 150%), both the X & Y positions of the brush match the stylus position in all applications (Gimp, Photoshop, Clip Studio Paint). Setting the Primary display back to 150% for scale and layout causes the Y position of the brush to appear at approx. 66% of the stylus tip position, but it only occurs in Gimp; the other applications function correctly.
Is the bug reproducible? Always
Expected result: Both the X&Y position of the brush match the stylus position.
Actual result: Only the X position of the brush matches the stylus position. The Y position of the brush is only approx. 66% of stylus position.
