--- Comment #9 from Sebastian gustep12@yahoo.com --- I also just compared the following:
Wine 1.8-rc2 32bit with PCB123.exe and drawing PCB123-v2-complex-testfile-nofill.123
ClientSideGraphics=Y Result: 1.8-rc2 gives much improved appearance and response due to more regular buffer flushes. However, it still appears a little slower. When continuously zooming with the mousewheel, some elements are occasionally missing for a short moment - maybe for 50ms - 200ms at a time?
ClientSideGraphics=N Result: Still the fastest response. When continuously zooming with the mousewheel, the response is fast, and the entire drawing is stable (no elements are lagging).
I think both options are o.k., but please preserve the option to set ClientSideGraphics=N for special cases.
