Drawing with pen delayed image
GIMP version: 2.10.0
Note: bug reporters are expected to have verified the bug still exists either in the last stable version of GIMP or on updated development code (master branch).
Operating System: [Windows 7 Enterprise]
Package: [Download from gimp.org https://download.gimp.org/mirror/pub/gimp/v2.10/windows/Gimp-2.10.0-setup-2.exe (2.10.14 did not work on this machine so I used an older version.]
Description of the bug
Please describe your issue with details. Add screenshot or other files if needed.
Reproduction
Is the bug reproducible? [Always]
Reproduction steps:
- GIMP 2.10.0 New file or open existing image
- Select Pencil tool
- Draw line with Huion Inspiroy Q11K V2 tablet (Drivers reinstalled from Huion.com/downloads yesterday.)
…
Expected result: Line drawn from A to B
Actual result: Dot appears at A, No line appears as the pen moves on the tablet. At B if the pen remains stationary on the tablet no line or menus appear. Once the pen is lifted from the tablet surface the line appears along the track taken by the pen. Any pressure variation during the stroke is correctly rendered.
Additional information
The same behavior is seen with the brush and the eraser. Using the same tablet and pen and a concurrent session, the line drawing performance is as expected in MS Paint.
