Can you confirm if display scaling is used? And if so if it goes away when scaling is at 100% or 200%? (In reply to David Edmundson from comment #1) > Can you confirm if display scaling is used? > And if so if it goes away when scaling is at 100% or 200%? Yes, I used scaling. Flickering doesn't seem to occur at scaling levels of 125% or lower (including 100%), but becomes clearly noticeable at scaling levels of 150% or higher (including 200%). 🐛🧹 ⚠️ This bug has been in NEEDSINFO status with no change for at least 15 days.

Install the same operating system and desktop environment using the aforementioned hardware and drivers. 2. Use a resolution and refresh rate of **3840x2160@165** *(note: the issue cannot be reproduced with other display modes)*. Enabling HDR may help reproduce the issue more reliably. 3. Run applications in **full-screen mode**, such as Firefox or Kate. Playing a video in full-screen mode in Firefox can better trigger the issue. 4. At this point, the calendar, clock, notifications, volume control, and other elements in the bottom-right corner of the taskbar may intermittently cause flickering in that area. 5. If the issue cannot be reproduced, try rebooting the system and repeating the steps. ## 不能复现的情况 1. 3840x2160@165以外的分辨率和刷新率。 2. 使用开源驱动程序。 3. 不是全屏使用应用程序。 ## Conditions Under Which the Issue Cannot Be Reproduced 1. Any resolution and refresh rate other than 3840x2160@165. 2. Using open-source graphics drivers. 3. Running applications in non-full-screen mode. ## 结语 以上是全部信息，希望大家可以解答一下是什么情况，是否需要报告bug。 ## Conclusion The above contains all available information. We hope someone can help identify the cause of this behavior and advise whether a bug report should be filed.
