CoCo with Windows debugger
Incorrect behaviour
I will be opening a PR shortly that fixes both problems
Problem 1) If the main Windows Debugger window is resized to be narrow enough to force a horizontal scrollbar for the disassembly pane, then horizontally scrolling that disassembly pane left & right can cause strange garbage to form. In the first pic, you can what the right-side comments should look like. In the second pic, the window is narrowed. In the third pic, the narrowed window is scrolled right, and the comments are garbled.
Problem 2) If the comments feature is used within the disassembly pane, comments might easily exceed 50 characters. When this happens, the right end is clipped off without any ability to scroll the clipped characters into view or to widen the window. The rightmost characters are effectively inaccessible.
NOTE: I have observed the above problems on the MAME Windows Debugger under Windows. I briefly tried the QT Debugger under Windows: Problem 1 occurs, but Problem 2 seems ok. I briefly tried the imgui debugger, but it crashes every time I click on it. I do not have access to MacOS or Linux.
Expected behaviour
Problem 1) No garbage!
Problem 2) The debugger window should adapt to longer lines due to comments, and allow the user to scroll them into view and to widen the window to show more on screen at once.
Steps to reproduce
- Run MAME coco2b -debug on Windows. I expect any debuggable emulated machine will exhibit the problem, but coco2b is what I use.
- Follow description from "Incorrect Behavior".
