These could last anything up to around 15 seconds. It had proved impossible to find a pattern to the behaviour. I could have been suffering from this for hours, then suddenly one or two messages would depart promptly. All this was on the Acer Aspire One, which has an Intel Mobile 945GME Express graphics unit. I had desktop effects enabled, but was only using 'dim inactive windows'. Two days ago I decided to try changing the compositing type from OpenGL to XRender. The improvement was immediate and obvious. It isn't perfect, but it's a great deal better. I know that information is being gathered about various display card problems. I want to add this one to the collection, and to point out the workaround. FWIW, at least one other user that I have talked to has had a similar result though the details differ. He will add his information to my report. Anne -------------- next part -------------- A non-text attachment was scrubbed...
