Fluxbox disimprovements on dual monitors

Hello,

It took me more than +1 year after Debian 9 being EOLed to finally switch to Debian 11 AntiX due to so many custom apps and so many issues.

Regardless the security patches in the new system, when one upgrades he/she expects to get a "better" product not something utterly crap with bloatware features nobody asked for. Anyway if I wouldn't upgrade none of the latest browsers firefox/chrome would support the OS soon.

My new setup is:

Fluxbox 1.3.7 : (c) 2001-2015 Fluxbox 

00:02.0 VGA compatible controller: Intel Corporation Skylake GT2 [HD Graphics 520] (rev 07)

xorg-server 2:1.20.11-1.0nosystemd3 (https://www.debian.org/support) 
Current version of pixman: 0.40.0


There are some extremely annoying issues compared to running Fluxbox on the exact same laptop but with the old system:

With a 2 monitor setup moving maximized windows make it switch like crazy in between the virtual desktops, sometimes it ends up positioning the window outside the area then you have to kill the process and reopen it. This was not happening at all on the old system.

Also this might not be related to Fluxbox but moving video players like VLC between the 2 screens makes the running video sluggish, this was also not present with the old Debian and old X.



I wonder if Flux is still being developed... it would be nice to have a proper taskbar per monitor option. It can do taskbar on specific heads or on ALL but when you select ALL it just makes a huge taskbar and put the apps in order when you started. Having 2 taskbars on the 2 monitors would be better with each only displaying the corresponding apps.
