We also have the issue of blu_ue4_process.exe surviving Unreal exit at times. This suggests our cleanup is not fully wrapped.

It's worse than just texture release, it appears that the browser renders incorrectly (patches/deltas) onto the page vs what 5.1 & 5.3 show. Update textures needs a change, did API change?

5.3 render:

5.4 render:

(bbc re-render trigger caused crash)

looks like last patch (lowest) override other patches

[getnamo]

UpdateTexture2D changes (5.3->5.4):

Appears to use a block copy architecture, potentially a source of the problems?
