Excellent. That definitely fixed it. Thanks for your help!

Hi inmarket, Thanks for the quick reply. I put together a quick test program that shows the issue. It can be found here: https://bitbucket.org/rabryan/ugfx-test-arcs It just draws to non-filled rounded rectangles on a black background. Each rectangle has a missing pixel at the end of each corner arc going clockwise.

I'm developing some code running on an Embest-STM32-DMSTF4BB board with SSD2119 LCD that draws a lot of rounded rectangles. I had been working off the master branch from a commit in early October. I just recently updated to the latest commit on master (bca78196) and the drawing of the rounded edges of the rectangles has degraded somewhat. For each edge, the drawing of the arc is not complete -- it skips a pixel just before rejoining the right angled lines of the rectangle. This results in 4 blank pixels in each rounded rectangle. Its not a resolution issue either since the missing pixels are colinear with the straight edges of the rectangle (i.e. they're on the same row or column of the straight edge line). Have there been changes to the gdispDrawRoundedBox() or gdispDrawArc() code that would account for this?
