Title:
Vulkan applications cause permanent memory leak with Intel GPU
Status in Linux:
Unknown
Status in linux package in Ubuntu:
Confirmed
Bug description:
Vulkan applications, as Dota 2 and DXVK games cause a memory leak
where memory is never freed and can cause a system crash if the
applications are used for long enough. Certain applications can make
the leak be as high as 10 MB/minute.
Details about this bug can be seen at
https://github.com/doitsujin/dxvk/issues/632 and

This bug was fixed in 4.19-rc6 and was backported to 4.14 and 4.18.

drm/syncobj: Don't leak fences when WAIT_FOR_SUBMIT is set
commit 337fe9f5c1e7de1f391c6a692531379d2aa2ee11 upstream.
We attempt to get fences earlier in the hopes that everything will
already have fences and no callbacks will be needed. If we do succeed
in getting a fence, getting one a second time will result in a duplicate
ref with no unref. This is causing memory leaks in Vulkan applications
that create a lot of fences; playing for a few hours can, apparently,
bring down the system.
