Hi,

I have the same issue. I tried 3 machines with ubuntu 18.04.1 with a self-compiled Pd 0.49.0 and Gem 0.93. cloned from git.
One machine has an Nvidia Geforce GTX 660 Ti and it has no problems. The other 2 machines have an Intel integrated graphics controller and they crashed after recreating gemwin only when the text3d is used. With text2d there's no problem, same with other gem objects.
pd -verbose -lib Gem:
i965: Failed to submit batchbuffer: No such file or directory

Best, A.

to correct my previous statement, when I wrote metro is slower 3 times I was wrong, it is not 3000ms but 3333ms but it is due to my last project where I used 200fps for the Pylon high speed cameras.
now everything seems to make sense: when I used those USB3 cameras with the correct 200fps, this metro phenomenon did not occur, until I changed the cameras to webcams keeping accidentally the 200fps. when turned it off Gem went back to 20fps.
Thanks for solving this mysterious case :)

yes you are right, once it was 3 times slower, once it was 3 times faster.
Gem is on default framerate, I guess you mentioned it is 20fps.
Monitor is on 60Hz. There is a ratio of 1:3 indeed but I hope it has nothing to do with metro.

i'm a bit confused now:
in your last thread you stated that the metro was exactly 3 times faster
(that is a [metro 1000] running a 333ms; now a [metro 1000] is running
at 3000ms).
while a slower/faster metro is entirely possible and te two problems
might be unrelated, i wonder why exactly the same factor "3" occurs in
both issues.
could it be that the problem is somewhere else (e.g. a simple patch error?)

at which framerate is your Gem-patch running? at which framerate is your
monitor running?

afaict, this is unrelated to the crasher bug you are describing.

i'm not sur what you mean by this.
