21014) Source code disply only assembled code from vasm with option -dwarf
21115) After a new breakpoint set, the breakpoint list window is not refreshed
212-- User must perform an operation, such code tracing, to see the breakpoints list update
21316) Some ASCII characters may be not displayed correctly
214-- It depend how the text is displayed, this is related to the QT/HTML encoding done when reading DWARF file
24470541 21517) Potential legacy crash when leaving emulator in pause mode for a long period of time
217Cosmetic / UX issues
2191) The SP (Stack) icon color backgound doesn't look similar with the other ones
