System Information
Windows 10 Pro
AMD Radeon HD 7970

Blender Version
Broken: v2.80.23 c3d46694e2

Short description of error
The build downloaded from https://builder.blender.org/download/ crashes as explained so I decided to built the blender2.8 branch in Visual Studio 2017 to debug and see what error it gives and here's what appeared in the console after it crashed:
GPUTexture: texture alloc failed. Not enough Video Memory.
And in Visual Studio it stops at GPU_texture_format by throwing a "read access violation" exception. Here's a screenshot:

Exact steps for others to reproduce the error
I just open Blender 2.80 with all factory settings, delete the cube, add a GP Monkey, create a new 2D drawing workspace and start changing the colours of the materials and after a few seconds of dragging the mouse in the colour wheel (or any other part that changes the colour in real time) it crashes.

Comments
I reckon it's due to my GPU not being supported anymore, but I don't think it should crash like that anyway since it works fine for a few seconds (albeit a bit slow even with just Suzanne) before going kaboom. Looking at my GPU's memory in the task manager doesn't show me much of an increase. It's actually possible to keep it working for a little longer if I don't spend much time selecting the colour. It seems to crash once a certain amount of time of messing with the colours is reached.

Damn, why do I only find similar questions after asking... I searched before posting but didn't see this one.

No clue how to close or merge it now.
