[PD] pix_snap2tex: First frame garbled upon repeated launch?

[Peter P.]

Hi list,

having fun exploring Gem's [pix_snap2tex] object, I find that the first
frame to be snapshot is garbled and displaying a green bang and the text
"Pd" unless opened the first time (see screenshot). This is on Debian
with Gem 0.94-3.  Attaching a minimal working example. Can anyone
confirm this and is it worth a bug report? Any good workarounds apart
from adding things to the render chain which zero out the first snapshot
frame etc?

thanks and thanks!
P
