On the current Linux32 Pharo 7.0, (https://get.pharo.org/70+vm as of 30 minutes ago) the VM crashes with the message XIO:  fatal IO error 14 (Bad address) on X server ":0" whenever I try to enlarge the Pharo window by dragging the corner, and get to a size of about 2Mpixels. This is with a virgin image with no windows open inside the main window. A workaround seems to be to open a System Browser before resizing the main window. This does not reproduce on Pharo 6.1 (https://get.pharo.org/). This *does* reproduce when running the Pharo7 image on the Pharo 6.1 VM, so it may not be entirely a VM problem. Most times, no crash dump is created, and nothing is logged to PharoDebug.log. Occasionally, especially when rapidly changing the size of the window, it segfaults and logs a dump. This may or may not be the same problem.  This is less annoying since I found the workaround, but still seems to be something that should be fixed. Does anyone want further information from me in order to fix it? Regards, -Martin
