[2.1.7] Disabling texture compression produces a recurrent lag spike.

[dupraz]

Even while idling, with nothing on screen, where no fetching from the RAM-cached atlas should be happening. This seems to be an issue with texture streaming, because otherwise the game is playable normally, without DXT artifacts.

Configuration:
[graphics]
video-memory-usage=all
texture-compression-level=none

For reference, this does not happen when the atlas fits entirely within VRAM and texture streaming is disabled.
For example, on the same scene, with the space-age mod unloaded (even as these sprites aren't rendered or used on the current scene).
