Scroll wheel over Opacity input field only affects selected object if the input is NOT focused
- Switch to the CPU preview, or use the GPU preview and turn off 'real-time drawing & editing'.
- Make an object. Keep it selected.
- Hover your cursor over the opacity numeric input box in Transparency or Properties. Play with your scroll wheel. Watch the opacity change.
- Click in the input box. Keep the cursor over it. Play with your scroll wheel. The number changes but the object does not, until you hit return.
- Try this in Illustrator 2020. Observe that in both steps 3 and 4, the object changes opacity regardless of whether you click on the opacity input box or not.
The settings in the Performance pane of the prefs interact with this:
If the GPU preview is on, this only happens if 'real-time drawing and editing' is off.
If the CPU preview is on, this always happens regardless of the status of the real-time drawing switch.
I observed this on a Mac running OS 14.7.6 and Illu 29.3; this change happened somewhere between 24.3 and 29.3. I just checked 27.8.1 and it has the new, undesired behavior as well. I'll see if I can get the person who brought this glitch to my attention to report their operating system and Illu version here as well.
This may affect other input boxes, I tried a few different stroke weight boxes and it does not affect them. The original discoverer suggested that other input boxes are affected but only listed the opacity.

Tested in Beta 29.8.0.10
With Real-Time Drawing and Editing ON
GPU: the object is updated in real time both with the field focused or not
CPU: updated only with non-focused fieldWit Real-Time OFF
GPU: updated only with non-focused field
CPU: updated only with non-focused fieldOther fields I tried, like Width, Height, Stroke Weight, update the object regardless of the focus.
In CC 2017 Opacity also gets updated for both states just fine.I think it’s a bug. Scrolling once over a value is a complete finite operation, no matter if the field is focused.
