Today marks my first day's experience with blender. Complete newbie here. I've been following a tutorial on building simple characters and getting familiar with the work space. I noticed something right away when switching between the various modes. Wireframe, Solid, and even Render Preview modes work without a hiccup (most of the time) but when viewing Dev Mode, I get crazy artifacts, shapes and colors. This WILL happen to a fresh blank General document with all settings set to default. Switching back and forth will cause the effects to change each time I go back to Dev Mode, and eventually when switching to Render Preview Mode. Ive seen people with mostly similar problems but it seems that none of the fixes are working. I've tried tweaking light and shadow settings, and some settings under the Shading tab. The effect happens in:
Eevee engine, Look Dev Mode
Eevee engine, Render Preview Mode (Happens once I switch from LDM)
Cycles, CPU Device, Look Dev Mode
Cycles, GPU Compute Device, Look Dev Mode
I've included two images. One is a screen shot of the tutorial , and one is what my screen looks like within the same window within Blender, along with my computer's information.
So sorry if it's something simple and I've overlooked it. I gave it my best to try and solve it myself. Let me know if any more information is needed. Thank you!
