Minor redraw problem in 'Info' window when scrolling using trackpad

[mdudziak]

The problem is that the Info window does not redraw correctly and ends up getting highlight ring artifacts when scrolled using two-finger scrolling on a MacBook Pro. Does not happen (for me) when using the scroll bar or moving the scroll thumb. To reproduce:

• Open the Info window for a contact (right click contact and select Get Info)

• Click on the address book icon on the top

• Click on the notification icon (the red police light icon) on the top

• Scroll down and then scroll up using two finger scrolling (important as I cannot reproduce using scroll arrows or using the scroll thumb. MIGHT work if using a scroll wheel but I do not have one to test)

• Note the artifacts left by the highlight ring around the icon.

See attached image for an example of the problem.

I should note that this is 100% reproducible for me.

I cannot reproduce this, however I have been able to reproduce a seemingly related issue (for many months) wherein the 1px border/divider between the 'tabs' for the inspector and the list of events disappears when scrolling down. The only place it remains is between the scrollbar and the tabs.

Odd. I have no trouble reproducing this, though as I indicated in the original report I only see it when I use 2-finger scrolling on my MacBook Pro. Don't see it when using the scroll thumb or scroll arrows. Also, it is important to select an icon other than the notification icon (the red light) then select the notification icon again. This causes the icon to get the focus ring around it (the icon does NOT have a focus ring when the window is first opened).

It is not a big deal, obviously. Just a very minor annoyance.

mdudziak: what version of OS X are you using?

This happens when you have keyboard control set to "all controls" (focus ring around segments at the top) and slowly scroll with the trackpad, which means something is clipping weirdly.

I'm running 10.5.7.

YES! Good catch.

Toggling keyboard access off makes the redraw problem go away for me. I also find that if I scroll very slowly I see the problem, but even if I scroll fast I see the problem (just looks different). I don't use full keyboard access anyway so I'll turn that option off.

Thanks, Matt

I have set my keyboard controls to "all controls" and attempted to reproduce, but could not. The problem I had mentioned that is very similar is also not reproducible any longer with 1.5hgr2776 05e1 (last four of hash) on 10.6.1.

Can anyone else still reproduce this?

[mdudziak]

I am no longer seeing this as well, though I have since upgraded to Snow Leopard.

I'm able to reproduce this every time with the exact same steps as noted in the OP. I'm also seeing it inside the Chat Transcript Viewer when searching through logs and having the bar active.

Seeing this in 1.4 and 1.5b9 whilst using a Magic Mouse to scroll.

Toggling the keyboard controls as suggested above fixes nothing and the problem is still present.

This only happens with the Lion type scrollbars. With the old type the bug does not show.

According to CFM these glitches could "be caused by the view not being sized correctly (non-integral bounds, or not-/over-filling its containing scrollview, iirc)". Might be worth investigating so as to achieve a more appropriate fix.
