Wow - believe it or not, you're the second person in a week to figure out what triggers this particular bug (which has been a nagging mystery for months)! I tracked down the root cause a few days ago - it was due to my calling MatPlotLib's draw() method twice in one iteration of the graphics loop (on first showing the plot and then at any resize). The first draw was meant to cache the contours as a background image that the scatter plot gets redrawn over. As near as I can tell, what happens is that the draw() method runs as a separate C++ thread and doesn't enforce thread safety, creating a race condition: if the second call happens before the first is done, it'll delete the drawing while the first thread is still writing to it making things go kaboom. Anyway, I've fixed this in my code, and it'll be in the next release - if you want to hotfix it in the meantime, you should be able to copy the file at https://github.com/tristanic/isolde/blob/master/isolde/src/validation/ramaplot.py over the one in %localappdata%\UCSF\ChimeraX\0.93\site-packages\chimerax\isolde\validation.

Actually, come to think of it: *don't* do that. I've made some other changes that will break things (they're dependent on changes in other files). If you're really keen, you could just apply the specific edit at https://github.com/tristanic/isolde/commit/c66180ae52523e9fd7f6eb3dd6dfee0fdeedc7e6. On 2020-05-15 16:51, ChimeraX wrote:
