Memory leaks when calling gpu:setBuffer() indefinitely

[tljk]

Describe the bug
When continuously call setBuffer, the task manager suggests a significant and linear increase of ram usage. If I remove the skip() part, it increases so fast and eventually causes oom and crash the game. I believe it's a bug because GPUT2 does not have such behavior and the ram usage persists even if I stop the code.

To Reproduce

local gpu = computer.getPCIDevices(classes.GPUT1)[1]
local screen = computer.getPCIDevices(classes.FINComputerScreen)[1]

event.listen(gpu)
gpu:bindScreen(screen)
gpu:setSize(150, 50)

local buffer = gpu:getBuffer()
buffer:fill(0, 0, 150, 50, " ", nil, {1, 1, 1, 1})

while true do
	gpu:setBuffer(buffer)
	gpu:flush()
	computer.skip()
end

Expected behavior
Ram usage should be stable

I think this might be caused by set buffer allocating memory faster than the UC garbage collector can handle it. If you stop the program and wait, does the ram go down or stay high? The latter hints to a memory leak.

Would not go down a bit after I stop the code, and that might be the point as you have suggested.
