Debian 9 testing
KDE 5 Plasma
Krita 4.2.0-pre-alpha git 1af5c34
Wacom Intuos 3 A4

When I leave canvas using wacom pen to select color I lose sight of the cursor, until I tap the pen to click.
If I use mouse to select color I need to move the cursor back on canvas for the cursor to not be system but the outline cursor.
On-Canvas HUD sometimes doesn't show cursor while using wacom either.

Bugs should go to bugs.kde.org under the product Krita, we cannot track them in the forum.
