p.s., I don't know if it will help, but I have found the issue is predominant on the left-side, secondary display running at 150% scale. See screenshot below...
Basj, Per your instruction(s), I uninstalled (with settings deletion / removal), rebooted, reinstalled (new beta version: 2.52.3), and rebooted again. The issue returned as soon as "Let Start11 enhance the taskbar" was turned on. Also, I enabled this setting and noted the issue, before restoring my personalized settings.
