FP3 logcat spammed (9 per second) with: HWPrimary::SetRefreshRate: Failed to open /sys/devices/virtual/graphics/fb0/dynamic_fps
- /e/OS version: 2.9 (at least present since 2.8)
- Device model(s): FP3(+)
- Impacted Application: logcat
## The problem
`logcat` is spammed with the following message. About 9 occurrences per per second on an idle device.
```
05-13 01:24:10.366 543 543 E SDM : HWPrimary::SetRefreshRate: Failed to open /sys/devices/virtual/graphics/fb0/dynamic_fps with error No such file or directory
```
**UPDATE: Duplicate #8224**
Seems there may be a [LineageOS fix](https://review.lineageos.org/c/LineageOS/android_kernel_fairphone_sdm632/+/383834) which could be cherry-picked.
**Can I somehow make a pull request?** Seems I can't clone the [android_kernel_fairphone_FP3](https://gitlab.e.foundation/e/devices/android_kernel_fairphone_FP3/-/blob/2570422a6f2a017cf5594aba5f28007091afada1/drivers/video/fbdev/msm/mdss_mdp_overlay.c#L6733) repo to make a pull request, because this GitLab instance tells me:
`You cannot create projects in your personal namespace. Contact your GitLab administrator.`
**Steps to reproduce**
1. installed [IMG-e-2.9-t-20250321478215-official-FP3.zip](https://images.ecloud.global/official/FP3/IMG-e-2.9-t-20250321478215-official-FP3.zip), including wiping the device.
2. do the initial setup with default values, skip whatever is possible (no WLAN configured, ...)
3. open system settings to enable developer mode, USB debugging and root debugging
4. connect a PC via USB and run `adb shell logcat`
5. don't let the phone's screen turn off
