New submission from Tal Einat <talei...@gmail.com>:
With code context shown, scrolling a window by dragging the scrollbar causes the scrollbar's tab to "jump around" and sometimes some "flashing" visual artifacts. The "flashing" appears to occur only before the screen is resized for the first time, in which case the entire window is resized whenever the number of context lines changes during scrolling. See attached animated screen capture. Reproduced on latest versions of Win10 and macOS. See also PR GH-14030, adding line numbers, which makes this more likely to occur for users. ---------- assignee: terry.reedy components: IDLE files: code-context-scolling-compressed.gif messages: 347666 nosy: cheryl.sabella, taleinat, terry.reedy priority: normal severity: normal status: open title: IDLE: Scrolling issues with code context shown versions: Python 3.7, Python 3.8, Python 3.9 Added file: https://bugs.python.org/file48469/code-context-scolling-compressed.gif _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue37559> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
