(Video example)

(Krita appimage 4.2.0-pre-alpha (git d4a8064) - Ubuntu 14.04, Unity)

In latest nightly build the cursor gets stuck on the "col-resize" icon (https://www.w3schools.com/csSref/playit.asp?filename=playcss_cursor&preval=col-resize) when hovering the UI dockers ("Esc" key works to unblock).

(see video)

[^ Gif anim to show I can't reproduce the bug ]

I tried and can't reproduce here on Git~master(539f7d07e).
But my setup is a bit different. I have only one "Shade Selector" slider. I tested with two, same. (gif in attachment) Kubuntu 18.04.1, Nvidia proprietary driver, Plasma D.E.

Yes, this is related to the nightlies currently using the QT xcb implementation instead of Krita's own(this requires a cmake option), because it resolves some linux tablet bugs... it however does introduce the os x tablet bugs :p

Anyway, confirming(for me it stays stuck in the arrow), and changing the name so it's easier to find later.

I don't see the cursor stuck, but painting gets broken.
