libinput does not send TABLET_TOOL_TIP down event until 5% pressure is reached on non-Wacom tablets
In Krita and other illustration programs, I cannot start a stroke with any less than 5% pressure. I can end a stroke with less, just not start one. After looking around for quite a while, I've come to believe that the problem lies in libinput, and sudo libinput debug-events
does register pressure below 0.05 but doesn't send out a “down” event until 0.05 pressure is reached.
Attachments:
Relevant stuff is all in the attachments, libinput-debug-events.log
is most useful here because it contains the “down” marker that indicates the bug pretty clearly.
- I'm currently experiencing this problem on an XP-Pen Artist 15.6 Pro using their new proprietary driver, and previously had the same problem with a Huion P608N using the Digimend drivers.
- I have not set any custom settings for my tablet.
- I'm using the libinput10 package from Debian, dpkg version: 1.13.4-1
