When autohide is enabled and transparency > 0, the panel blinks when you leave the panel. So probably those steps are not applied at the same time. When a transparency of 100 can be chosen the panel is completely hidden when you leave it and the 2 separate steps are not visible anymore (and also the hidden panel line). Reproducible: Always Steps to Reproduce: 1. Enable autohide 2. Enable transparency 3. Enter panel 4. Leave panel Actual Results: The panel become transparent first and is then hiding. Expected Results: The panel is completely 100 transparent and you dont see the hiding step. 95 -> 100 trans in the property window.
Ok, done. That was the last time I changed that particular limit... I hope ;-)
