Why close?

offalynne commented 9 months ago

Uncertain on repro steps and didn't want to be a bother :-) don't let me get in the way if you'd like to take a look !

hrydgard commented 9 months ago

Hm, do you mean that it doesn't always happen? Also does changing the backend to Vulkan or OpenGL help?

Also, can you take a quick screen recording?

It is fairly consistent

Also does changing the backend to Vulkan or OpenGL help

Several people say yes, from what I have seen, no. The only sure solution seems to be downgrading.

can you take a quick screen recording

I've been unable to clearly capture it as it happens sporadically and doesn't compress well but it's fairly obvious after playing even briefly. Here's a stream clip: https://clips.twitch.tv/InquisitiveLitigiousCobblerSuperVinlin-HrheotynYdHRwOtJ

Downgrading to 1.13.1 helps? Interesting.

It's not the vertex cache option (which is now gone in the latest builds)?

hrydgard commented 2 months ago

Hm, the video clip is gone. Is this still reproducible?
