Spiking processor from selecting non-adjacent cells in Calc
Confirmed on: Versie: 6.0.3.2 Build ID: 1:6.0.3-0ubuntu1 CPU-threads: 4; Besturingssysteem: Linux 4.15; UI-render: standaard; VCL: gtk3; Locale: nl-NL (nl_NL.UTF-8); Calc: group I noticed two things: 1. The speed of selecting the non-adjacent cells (with CTRL) makes a difference. When selecting very fast, Calc cannot follow the process after about 5 cells. When selecting slow, it an take up to about 25 cells before the extreme slow down starts. 2. One processor thread spikes when this happens. See the screen-region picture I added. Duping to a newer one as it has more data/testing info. *** This bug has been marked as a duplicate of bug 121860 *** |
