SUMMARY The tooltips from a window's titlebar are rendered with transparency issues around the corners. Normally they are cleanly rounded but for some reason any from the titlebar itself are not. The appearance is very slightly different depending on where the tooltip appears on the screen which leads me to believe it might be a graphics related bug potentially specific to my hardware. STEPS TO REPRODUCE 1. Open any window 2. Hover the cursor over an element to produce a tooltip 3. Look at the corners of the tooltip and observe that they are not perfectly round with soft edges but instead contain miscoloured pixels.

I've attached some example images to illustrate the issue. - Examples 1 and 3 are "clean" demonstrating the correct appearance. These tooltips come from Dolphin. - Examples 2 and 4 are "ugly" and come from the top-most portion of the titlebar, hovering over the top-left icon and top-right close window button. If you zoom into the images you'll notice the discolouration in the corners.
Closing as this no longer appears to be an issue
