Description Tom Colley 2018-04-10 03:33:05 UTC
I observe that Calc (V5.1.6.2) seems to do multiple redraws during the window resize operation. This works fine for small simple files. For larger files, with higher processing loads, it is a problem. I find that after a resize operation, I can wait from 1-30 seconds for the multiple redrawings to finish executing and catch up with the final window size. I think this redrawing includes multiple recalculations of formulas, of which VLOOKUP is noted for being particularly demanding. The queuing and execution of multiple redraws seems completely unnecessary and makes calc files, that are otherwise quite functional, difficult to resize. Could the redraw procedure be reworked so that there is no accumulation or queuing of multiple redraw or recalculate events?

This sounds like an old Ubuntu-only bug. As 5.1 is very old, could you try 6.0.x?
