I get a:
[1006/162049.528:ERROR:gpu_process_transport_factory.cc(990)] Lost UI shared context
Casparcg runs, but overload the cpu and ram, and is respond is slow.
In 2.11.8 NRK doing the same task, everything is fine.
what can I do?
best regards
Heine Froholdt
Do you use WebGL? Stackowerflow says this.
no webGL - but the error goes away if I start the server/scanner with the CasparLauncher - but the overload problem is not gone… (starting a new topic on that subject)
heine
the same thing happens to me when I run Caspar 2.3.0 LTS (without changing anything in the original configuration file) :

this comes from Chrome driver as DidiKunz points out in its link.
But I don’t use WebGL for my templates (I don’t use HTML templates)
if I add
<html>
<enable-gpu>true</enable-gpu>
</html>
the message disappears :

Hello,
Just to confirm that I hit this same issue while I configured other people’s server. Hardware is not my choice: Mac Desktop running Win 10, Decklink Quad, AMD Radeon HD 5700 (I know…, as I said hardware is not my choice). This happens right after starting Caspar 2.3 LTS server, before any client is connected:

I have tried adding:
<html>
<enable-gpu>true</enable-gpu>
</html>
it crashes on start, if I set it to “false” the same error apears, it’s obviously default value.
Anyone got to the bottom of this? Any hints?
Dear Friends, same error message.
Error:

Works ok for me.
Hello, I recently pointed at this issue, on booth my server.
Runing on 2.3.3 LTS and 2.3.0
When running the last beta, the error disappeared.
I tried to ad the tag
<html>
<enable-gpu>true</enable-gpu>
</html>
In the config file, but, when I tried to launch the media scanner it crashed at start.
Does anyone has a clue to solve this ?
Kind regards
