**System Information** Operating system: Windows-10-10.0.19044-SP0 64 Bits Graphics card: NVIDIA GeForce RTX 3060/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 516.94 **Blender Version** Broken: version: 3.3.0, branch: master, commit date: 2022-09-06 15:39, hash: `rB0759f671ce1f` Worked: never i think **Short description of error** Loading a brush alpha/texture on dense meshes takes very long. Especially when you do a brush before swapping out the brush texture again. If you don't do a brush stroke after loading a texture and directly load another one it will be done quicker. {F13528395} **Exact steps for others to reproduce the error** 1. Add a standard uv sphere and apply 7 subdivisions. You will end up with over 8 million faces. 2. Go to sculpt mode and add an image texture to the standard brush. 3. Do a stroke and load another texture/alpha -> long loading time (several seconds) and this will go higher and higher with more polygons 4. Now don't do a brush stroke and load another texture/alpha -> quick loading time Here are the textures i've used in the video to test. {F13528456}
