1623647 - Picture caching allocates a lot of GPU memory

Status: RESOLVED FIXED

(Core :: Graphics: WebRender, defect, P3)

Description

[Nicolas Silva [:nical]]

General observation that we dedicate a surprisingly high amount of GPU memory to picture cache tiles. The reallocation of the texture arrays for the tiles is costly (at least on intel). and things get generally slower when we are running low on memory (on intel).
