✅ An issue with converting byte array to a Bitmap with 32bppArgb image format

Hi everyone. I need help (desperately).
I'm creating a simple raycaster game, which means I need to clear screen and fill it again every frame.
I draw by puting color data into array and converting this array into a bitmap.
The following code sets bitmap pixel data to data taken from array.

Rectangle copyRect = new Rectangle(0, 0, Width, Height);
BitmapData data = imageBuffer.LockBits(copyRect, ImageLockMode.ReadWrite, imageBuffer.PixelFormat);
IntPtr bPointer = data.Scan0;
Marshal.Copy(buffer, 0, bPointer, buffer.Length);
imageBuffer.UnlockBits(data);

Rectangle copyRect = new Rectangle(0, 0, Width, Height);
BitmapData data = imageBuffer.LockBits(copyRect, ImageLockMode.ReadWrite, imageBuffer.PixelFormat);
IntPtr bPointer = data.Scan0;
Marshal.Copy(buffer, 0, bPointer, buffer.Length);
imageBuffer.UnlockBits(data);

Width

Width

and

Height

Height

are variables specifying size of the bitmap I want to edit.

imageBuffer

imageBuffer

is a Bitmap I want to edit.

buffer

buffer

is my pixel color data (

byte[]

byte[]

), stored in this order: BGRA. This array is reset every frame by setting all elements to zero.

Next, I draw

imageBuffer

imageBuffer

to the screen. It works fine as long as

imageBuffer.PixelFormat

imageBuffer.PixelFormat

Format32bppRgb

Format32bppRgb

.
And here comes my issue: when I change

imageBuffer.PixelFormat

imageBuffer.PixelFormat

Format32bppArgb

Format32bppArgb

, weird thing happens (as shown on the second picture). Image is glitched in a odd way, and the same happens to strings in the left up corner, which aren't being drawn on the buffer, but on the graphics, after the

imageBuffer

imageBuffer

is modified.

Some interesting notes (all experiments done with

Format32bppArgb

Format32bppArgb

pixel format):
- when I change order in the

buffer

buffer

to ABGR I get less blurry effect and blurrines disappears when camera is not moving.
- when I change order in the

buffer

buffer

to ARGB, blur gets stronger, but also disappears after few seconds of standing still

In both cases colors are off, because I changed order of channels in the buffer.

On the first picture you can see how it looks with
