SUMMARY *** NOTE: If you are reporting a crash, please try to attach a backtrace with debug symbols. See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports *** STEPS TO REPRODUCE 1. Start steam with `steam -pipewire-dmabuf` 2. Setup steam link with a pair client and host 2. Turn off hardware acceleration on the host 3. Setup a non steam game with target /usr/bin/gamescope Run in $HOME application: /usr/share/code/code ## I only tested vscode at the moment. 4. Go to the client steam application and start the steam 5. Go to the host settings and turn on hardware acceleration 6. Kwin crashes OBSERVED RESULT Software remote works but hardware acceleration crashes EXPECTED RESULT No crash. At least fail gracefully.

4. Go to the client steam application and start the steam Correction 4. Go to the client steam application and start the stream. Stream the game
This bug is simple. Steam will crash kwin when switch from software decode to hw decode during a dmabuf-pipewire stream. Kwin will be killed, you can start krunner and start konsole to retrieve the longs. Sometimes, kwin will restart itself. This bug is repeatable. I did not test other applications nor tested hw acceleration to software acceleration.
This should be fixed in 6.0
