Krita 4.1.7 does not encounter this problem.
Comment 2 Scott Petrovic 2019-04-05 15:39:44 UTC 
Does this only happen on a Surface Pro 4? I am testing git master on a Windows 10 + Huion device and am not running into this issue.

git 917d698 from Krita nightly builds (latest version till now) does not have this problem. Chances are this is fixed in some commits after the version in question.
