Lag spikes or crash when the the screen's refresh rate is too fast

This issue has been tested by me and one of my friend.

Here's how to reproduce this bug:

  1. have a 4 * 4 screen link to a computer
  2. run the code below
  3. lag spikes happen
  4. right click the computer -> game crash

you can also reproduce the lagSpike by deleting the "yield()" without adding "sleep()" to the code.
Lag spikes would also happen, and would stop due to [too long without yielding]

local gpu = peripheral.wrap("tm_gpu_0")

local start = os.epoch("utc")
local function yield()
    if (os.epoch("utc") - start > 1000) then
        os.queueEvent("yield")
        os.pullEvent("yield")
        start = os.epoch("utc")
    end
end
gpu.setSize(64,64,4,4,16)
gpu.refreshSize()
gpu.fill(0x006400)
gpu.filledRectangle(197, 1, 60, 256, 0x006400)
gpu.line(64,1,64,256,0x32cd32)
gpu.line(196,1,196,256,0x32cd32)
gpu.line(65,192,196,194,0x32cd32)
gpu.line(65,128,196,128,0x32cd32)
gpu.line(65,64,196,64,0x32cd32)
gpu.drawText(10,3,"512m",0x00ff00,0x008000,2)
gpu.drawText(10,64,"384m",0x00ff00,0x008000,2)
gpu.drawText(10,128,"256m",0x00ff00,0x008000,2)
gpu.drawText(10,194,"128m",0x00ff00,0x008000,2)
gpu.drawText(200,30,"VS",0x00ff00,0x006400,2)
gpu.drawText(200,91,"Entity",0x00ff00,0x006400,2)
gpu.drawText(200,155,"VS-E",0x00ff00,0x006400,2)
gpu.drawText(200,221,"SRC",0x00ff00,0x006400,2)
gpu.refreshSize()
gpu.sync()

local function regularLines()

    gpu.line(64,1,64,256,0x32cd32)
    gpu.line(196,1,196,256,0x32cd32)
    gpu.line(65,192,196,194,0x32cd32)
    gpu.line(65,128,196,128,0x32cd32)
    gpu.line(65,64,196,64,0x32cd32)

end

while true do
    for i = 65, 195 do
        if i == 65 then
            gpu.line(65,1,65,256,0x32cd32)
        else
            gpu.line(i,1,i,256,0x32cd32)
            gpu.line(i-1,1,i-1,256,0x006400)
            regularLines()
        end
        gpu.sync()
        yield()
    end
end

Here's my crash logs. Hope this issue can be fixed soon : D
