Description Raghavendra kamath 2020-06-10 14:25:01 UTC

SUMMARY
When user triggers the show color history HUD or the color selector HUD with a square shape (the one which fills entire color selector with square, it can be chosen from the second row in advanced color selector options) if the mouse moves even a pixel away from the edge of these HUD they disappear. This becomes annoying and breaks the flow of painting. 

I would request to have a 10 px border with either white or middle gray color to these color pickers and other HUD elements, so that they don't disappear  accidentally. this will enhance the usability of these HUD elements

STEPS TO REPRODUCE
1. Trigger show color selector and move the pen slightly to edge
2. trigger advanced color selector with a square shape selector without the outer circular hue ring and try to choose color from edge


OBSERVED RESULT
HUD disappears when the cursor stray even 1px away from the HUD edge

EXPECTED RESULT
there should be a buffer zone around the HUD to avoid this behaviour

I can confirm it closes a bit unexpectedly.

Comment 2 Tiar 2020-07-31 17:52:31 UTC

Maybe there could be border area around the color selector that when the cursor is there, the color selector fades out a bit to show that it will disappear if you stray away from it too much?

Re-confirming for 5.2.6. Technically not a bug, but definitely a UX-problem. Tiar's idea sounds good to me, having a transparent margin around the widget where you can move the cursor without the widget closing. Clicking the margin would close the widget and immediately draw on the canvas (if a drawing tool is selected), on top of also just moving the cursor further off to close the widget.
