When I have WebRender enabled, the weather model animation at
doesn't repaint correctly -- I just see one or two ticks of the animation and then the image just stays static, instead of seeing the entire animation run smoothly.
I'm running on Linux (64-bit) with Intel graphics, and I have force-enabled both OpenGL and WebRender.
In more detail:
Steps to reproduce:
- if needed, go to about:config and toggle:
layers.acceleration.force-enabled -> true
gfx.webrender.enabled -> true
and restart Firefox. (This is needed for me.)
- load https://www.tropicaltidbits.com/analysis/models/?model=gfs-ens®ion=us&pkg=apcpn24&runtime=2019021112&fh=24
- click the Play button above the map (the [>] button between the [<-] and [->] buttons).
the images smoothly change (at least once they're all loaded, which might be an issue over a slow network)
mostly, the images don't change, except if I move the mouse over the image and keep moving it (which causes a tooltip to repaint on top of the images)
If I flip the gfx.webrender.enabled pref back to false (its default), then I no longer see the bug.
