+    being off by one pixel when vertical ones are not also enabled. [@thedmd]
+  - Fixed X position of angled borders being off by half a pixel. [@thedmd]
 - ImDrawData: fixed a regression in 1.92.9 where legacy `ImDrawData::CmdListsCount` was always 0.
   Prefer using `ImDrawData::CmdList.Size` anyway.
