--- Comment #27 from David Edmundson <k...@davidedmundson.co.uk> --- I did some more graphics reset patches in Qt and I think our handling is wrong. The reset flag is set on until you call makeCurrent a second time, then it's cleared. We have a tonne of places, especially screen change handling code, that calls makeCurrent without a graphics reset check. My theory is that if we get in here, we could have a reset that we don't handle. I'll flood my kwin with qDebug and see if I can trigger that happening. -- You are receiving this mail because: You are watching all bug changes.
