# BUG: 100% GPU usage on idle

|
|
# The bug is triggered when an application that uses the discrete card is terminated.
|
|
# GPU usage returns to normal when the discrete card is actually used again
|
|
# (e.g. when an application with DRI_PRIME=1 is opened)
|
|
# Workaround: Open a lightweight app (kitty terminal) that can use the GPU. If
|
|
# the bug appears again, kill it and re-open it.
