[BUG] Windows 11 Taskbar thumbnail live previews show previously closed dialogs
When hovering over the taskbar icon of some applications then hovering over a window's thumbnail, the "live preview" will show dialogs that were previously open but have since been closed on some mac...
Update your graphics card driver and restart the explorer.exe process to fix the issue of thumbnail previews displaying residual content in the taskbar.
Hi Eorku,
Thank you for your answer.We tested the same scenario on another PC running Windows 11 25H2 (build 26200.8037) with GPU drivers from late 2025, and the problem persists.
The bug also affects Windows 10. And since Windows 10 is practically at end of life and runs on many older PCs that cannot receive new GPU drivers, I don’t think that proposed solution is correct.
This is clearly a Microsoft Windows bug, not a GPU driver issue.
