Raspberry PI 4 and Bookworm 64 bit and lazarus, no success

I tried Raspberry Pi 400 64 bits Bookworm. USB SSD.
Fresh install  went fine. Looks familiar. Nice photo of a Chinese fisherman!

I use my Pi 400 mostly for compiling my Lazarus programs, so I installed Lazarus from Add/Remove programs. Installs OK.
Not very speedy, but OK.

Command line compilation is OK.  Lazarus GUI applications are broken, for a very simple hello world form, there appears first an empty form and then the real form after a long wait.

Installing with fpcupdeluxe (aarch64) fails.

So Lazarus and Bookworm have to wait until the software catches up. Bullseye is fine for now.

Known issue. Seem to depend on windows manager being used. Try a search on these forums as here have been some fixes (not sure if they ended up in the source-tree). I have seen people mention up to 30 secs delay or smaller. I use bookworm on a intel machine with marco and no issues except once in a blue moon the main form tries to refresh itself about a zillion times before it is displayed. Activating the form (sometimes a small move to left or right) fixes that for me.

Ah, one of /those/. I don't have one of the latest RPis, but I have in the past seen problems where the window manager (AKA desktop environment) wasn't passing various metrics to an app which badly screwed up runtime decisions about window/pane sizes. I was able to get things properly by switching to KDE, but it was deathly slow.

This is clearly a Raspbian (or WTF they call it these days) problem, but they are reluctant to admit it and there's very little likelihood of a fix. TBH, I consider the issue and attitude together enough to make me reluctant to select that platform where an alternative exists.

In my case the problems predate that. I believe that they've quite simply missed chunks out of their display manager... the problem is that I've never found my way around the X11 protocol stack to be able to work out what one needs to probe that sort of thing.
