I have a problem with the appearance of tooltips when placing the cursor over a tool. As you know, there is a short 'hover' delay of about a second before the tooltip appears (which is fine) and then moving the cursor to another tool/brush/icon immediately shows the tooltip, all this is good.

However, the short delay is not triggered until the cursor is stationary over the tool icon. This is ok for the mouse, where holding it still is easy. With the graphics tablet pen, holding it perfectly still is not easy (not for me anyway). Krita knows where the cursor is and with the Toolbox tools it highlights the tool icon so it obviously knows that the cursor is over that tool. I'm wondering why you have to hold the cursor perfectly still before the tooltip delay starts (followed by the wanted appearance of the tooltip).

If there are any adjustment settings for these parameters then please tell me about them. I tried looking but couldn't see anything obvious.

Because that's the way tooltips work in Qt... Nothing we can tweak as far as I know.

Thank you for your early reply. I can understand why you can't make changes inside Qt.
If anyone else has this problem, there is a 'workaround' where you move the pen to place the cursor over the tool/brush icon and then lift it vertically so it's no longer registered by the tablet. Then the tooltip appears and you can place it back down to then move the cursor around to get tooltips for different icons. It's not ideal but it works.
