Kernel 6.18.3-200.fc43 causes VK_ERROR_DEVICE_LOST in vkd3d‑proton and a black‑screen hang when launching Cyberpunk 2077 on Intel Arc A770 (xe). Booting 6.17.12-300.fc43 fixes the issue; game launches normally and the error disappears.
System
- Fedora 43, KDE Plasma on Wayland
- GPU: Intel Arc A770 (DG2)
- Driver: xe (forced via kernel cmdline)
- Steam + Proton (tried Proton Experimental, Hotfix, GE; same issue on 6.18.3)
Regression window
- Worked on kernel 6.17.12-300.fc43 (game launches normally).
- Broken on kernel 6.18.3-200.fc43 (black screen on launch).
- Reproduced on Jan 10, 2026; confirmed fixed immediately after rebooting into 6.17.12.
Symptoms
- Launching Cyberpunk 2077 from Steam results in a black screen and hang.
- Proton log shows repeated VK_ERROR_DEVICE_LOST and swapchain failures under vkd3d‑proton on 6.18.3.
- Same game/proton configuration on 6.17.12 launches normally and no device‑lost errors appear.
Evidence
- Bad kernel log (6.18.3) contains repeated:
- vkd3d-proton: Device ... is lost (VK_ERROR_DEVICE_LOST)
- swapchain present/acquire failures
- Good kernel log (6.17.12) lacks VK_ERROR_DEVICE_LOST and only shows benign vkd3d warnings (pipeline cache misses).
Repro steps
1. Boot kernel 6.18.3-200.fc43
2. Launch Cyberpunk 2077 from Steam (any Proton version)
3. Observe black screen/hang and VK_ERROR_DEVICE_LOST in Proton log
4. Reboot into kernel 6.17.12-300.fc43, repeat launch
5. Game starts normally
Expected
Game launches successfully as it does on kernel 6.17.12.
Reproducible: Always
