does anyone notice that 2.5.1 visual speed is getting worse
compared to 2.4.2.4? populating grids, moving window, slashes
are all flickering and slow.
all
Which platform? Do you have any specific timings? How fast is your machine?

Robin, I've been thinking it was me, but maybe not. Unfortunately I haven't got any good benchmarks thus far, but subjectively -- especially when using wx.STC -- it does appear there's a bit of a slowdown. I still haven't converted all my stuff over fully so I still don't trust my impressions at this point.
I can supply you with entire apps that illustrate the as of yet (in my mind) alleged performance issues, but no simple code fragments as of yet.
Oh, and platforms here are W2K in both cases, one on a P4 1.6Gig, one on a P3 400MHz.
... Get thee down. Be thou funky.
it's a subjective matter i suppose, basing my eyes. but
since I interact with this particular instance of program
almost every day for 6 months now, I knew there was somekind
of slow down following the upgrade.
my platform: windows xp, python 2.3.3, wxpython 2.5.1.5
non-unicode, a compaq notebook w/ p4 1.8 Ghz and ancient
'radeon' card.
I was able to test on other computer running similar
os/python/wx but celeron 2ghz and some integrated vga, with
similar slowdown-ness not found on 2.4.2.4.
The slowdown was glaringly noticeable on grid redrawing. i'm
using a tablebase and have put a brutal optimization in
tablebase's getvalue-override calls to no more than a
getattr to attributes of list.
In 2.4.4, in a 20x5000 cells, scrolling the grid (inside
wxmdichildframe) does not exercise any noticable flicker.
yet redrawing in 2.5.1.5 is crawling--i could see the
bottom-up movement of cell redrawaing. But I have no problem
on small grid on both version though.
