Some odd things happening here whilst saving a large file - whilst saving the viewport display changes to a couple of steps previous (ie if one has just performed a trim the display shows the surface before the trim whilst saving) then reverts when saving process is done. No crash but disconcerting all the same.
This used to happen a long time ago, I remember it being a problem in… V4? Maybe early V5 WIPS? The discussion about it must have been on the old newsgroup. But it seems it was more or less fixed in V5 - or I just got used to it and don’t see it anymore… I do see some flickering of the display sometimes when saving large files, but not the complete reversion that I remember way back.
