Studio Display it's annoying to use now
The error occurs intermittently – most often when switching between applications that have a light background or when scrolling through web pages. At such moments, the monitor briefly flashes – in some cases once, in other cases several times in a row within a few seconds. Switching from dark content to light content almost always triggers the problem.
ProWe also noticed flickering when testing on MacBooku Pro with macOS Tahoe in versions 26.1 and 26.2. Neither update has improved the situation - on the contrary, users report that flickering has become more frequent in recent days.
Although the problem most often concerns Apple Studio Display, there are also complaints from users of other external monitors. This suggests that the bug may be related to external display support in general within the new macOS Tahoe.
