I can reproduce this on Fedora 29, GTK3.24.1, using SWT master as of today. I can't reproduce this issue, the time taken is the same (~530ms) when the lines are visible and not. SWT from master as of today Fedora 29 GTK3.24 |
Created attachment 192714 [details] Contains the Profile log, a screen showing the relevant infos and the modified snippet While testing my program the navigation with a SWT.VIRTUAL table scrollbar is very slow. The Table holds only 45000 rows and 15 columns. I've modified the Snippet144 to reproduce the problem. An increase of "COUNT" or "COL_COUNT" increases the slowdown. If you comment the "table.setLinesVisible(true);" (Line 45) out the lag goes away. A profiler shows gtk_main_do_event as the cause. (VisualVM 1.3.2 Log and Screen attached). On windows the program runs well even with very high values. Hopefully someone could look at this.
