[Lybrial]

Hi Guys,

I wanted to implement a grid toggle, I started with the vertical lines and tried it out.
Here the code, it is quite simple:

LybrialAnchors = LybrialUI:NewModule("Lybrial Anchors");
 
local LybrialAnchors = LybrialAnchors;
 
LybrialAnchors.grid = nil;
 
-- Initialize Addon
function LybrialAnchors:OnInitialize()
end
 
-- Get Options
function LybrialAnchors:GetOptions()
    return {
        toggleGrid = {
            type = "toggle",
            order = 1,
            name = "Toggle Grid",
            set = function(_, value)
                self:ToggleGrid(value);
            end,
            width = "full"
        },
    };
end
 
function LybrialAnchors:ToggleGrid(toggle)
    if (toggle) then
        if (not self.grid) then
            print("Create Grid");
 
            self:CreateGrid();
        else
            print("Show Grid");
 
            self.grid:Show();
        end
    else
        print("Hide Grid");
 
        self.grid:Hide();
    end
end
 
function LybrialAnchors:CreateGrid()
    if (not self.grid) then
        self.grid = CreateFrame("Frame", "Grid", UIParent);
        self.grid:SetFrameStrata("BACKGROUND");
    end
 
    local steps = 128;
    local width, height = UIParent:GetSize();
    local widthStep = (width / steps);
 
    self.grid:SetPoint("CENTER", UIParent);
    self.grid:SetSize(width, height);
    self.grid:Show();
 
    self:CreateVerticalLines(steps, widthStep);
end
 
function LybrialAnchors:CreateVerticalLines(steps, widthStep)
    for i = 0, steps do
        local region = self.grid:CreateTexture();
        region:SetColorTexture(0, 0, 0);
        region:SetDrawLayer("BACKGROUND", 0);
        region:ClearAllPoints();
        region:SetPoint("TOPLEFT", self.grid, "TOPLEFT", (i * widthStep), 0);
        region:SetPoint("BOTTOMRIGHT", self.grid, "BOTTOMLEFT", (i * widthStep), 0);
    end
end

Let me click the toggle input 5 times. The output is:

Create Grid
Hide Grid
Show Grid
Hide Grid
Show Grid

So as you can see the first time I enable the toggle the grid is getting created. After that the grid frame
is only showing or hiding. So it should work exactly as I want it to work.

But the problem is: On each `self.grid:Show()` the memory usage of my addon is increasing.
I toggled 50 times and my addon memory usage was increased by 25 MB.

I dont understand why a `Show()` on an already existing `Frame` is increasing memory usage.
Anything anyone can tell me about that?
