DRM/Radeon glxgears memleak log

Took a while to perform some more tests, and it turns out that running glxg=
ears
with amdgpu also leaks memory - launching a hundred of glxgears instances l=
eaks
about 400 megabytes, only freed after they are killed and the caches are
manually dropped with the command `echo 3 > /proc/sys/vm/drop_caches`.

Because glxgears does not need Vulkan support, it had also been possible fo=
r me
to confirm that the massive persisting leak is definitely caused by the amd=
gpu
driver - attached is a bcc memleak log of glxgears taken with the radeon
driver.

On a side note, launching vkcube seems to leak memory with the described ca=
ll
at a very similar rate as well.
