Using the method I documented in comment #16, I can still provoke the screen corruption.
De-maximising the individual source-file sub-windows has no effect, the corruption continues in the de-maximised sub-window. Re-maximising the sub-window similarily has no effect.
However, iconifying the complete Wine+SourceInsight window and de-iconifying it DOES clear the screen corruption, which is nice.
Version of Source Insight now at 3.50.0064
Version of Wine now at 1.1.44- 0ubuntu1~ lucidppa1
