I ran the following test with a script that logged memory usage in MB every
minute:
Automatic screen blank/lock was disabled, WhiteSur was enabled for GDM and
firefox, seconds visualization was enabled in the clock, text shadow was
enabled as described by Alessandro, and my cursor was hovered over the clock
for the duration of the test (which may or may not be necessary, but it made
the shadow more visible for me).
I observed the following over two 4 hour tests:
With 46.0-0ubuntu6~24.04.9 (unpatched): Starting memory utilization at
2025-10-27-08:54 was 394 MB, ending at 2025-10-27-13:21 was 559 MB, with
a roughly linear increase.
With 46.0-0ubuntu6~24.04.11 (patched): Starting memory utilization at
2025-10-27-13:24 was 385 MB, ending at 2025-10-27-17:40 was 387 MB,
utilization remained roughly flat throughout the test.
