--- Comment #5 from David Edmundson <k...@davidedmundson.co.uk> --- Ok, so. We've just had a graphics context loss event, everything resets fine and comes back up. We show a tooltip which was previously invalidated. We recreate it. QXcbScreen *screen = static_cast<QXcbScreen *>(context->screen()->handle()); QXcbGlIntegration *glIntegration = screen->connection()->glIntegration(); We crash somewhere in these two lines. Not clear where, but potentially it's to do with the tooltip not having a relevant screen associated it at the time of recreation -- You are receiving this mail because: You are watching all bug changes.
