GridPanel - rendering issue with a certain number of rows
I think theres a bug regarding the GridPanel in Opera 12.15.
You can see it clearly in the BigData demo:
or in the Cell editing demo:
To reproduce: Go into the Big data demo and scroll. Notice that only about 60 rows display correctly. The rest is invisible.
Or, use the cell editing demo, and add a lot of rows (about 50-60). You will notice, that the bottom rows will not display at all.
The examples above are working as expected if I set Opera to identify as Internet Explorer.
Thanks for the report! I have opened a bug in our bug tracker.
