[Mesa-dev] Empty files when dumping hud values selected with GALLIUM_HUD

[Julien Isorce]

Hi,

I noticed that GALLIUM_HUD does not write hud values into files properly.

The destination files look empty at least for 5 min and then are filed in
with some burst. I wonder if it could be a problem with the
GALLIUM_HUD_PERIOD which would be wrong when writing values into files. Or
write is not committed or not flushed.

I can see these values properly updated in the pane on screen but
destination files are empty for some minutes.

This is happening with various recent version of mesa + radeonsi. With
older mesa like 12.0.6, it is even worst, the destinations are not created
at all.

Does it happen for anybody else before I fill in a bug ?
