Taskbar on multiple windows monitors - some switch, some stay in the old mode (x64)

[nelscity]

Description

When it swtches from light to dark, my external monitor task bar goes dark, but my main display stays light. The taskbard text also goes into darkmode so I can't read it.

Expected Behavior

All taskbars on all monitors should go light or dark together

I have seen this behavior too. But not sure if it has to do with ADM or simply Windows...

I also have this problem, but it was fixable with enabling more aggressive dwm refresh in adm settings settings.

Found the setting, I'll try that, thanks!

It's usually both, but more on the Windows side. The issue was definitely not introduced by us, it's a Windows issue. But Microsoft surely has solutions for this which they will not share with us (or the PowerToys team for that matter, as that happens over there as well, at least last time I checked)

Yep, also issues on PowerToys:
