Anyone getting a WebGL fail after ~1 hr ? (Blackscreen in game and layout editor disappear)

Ive been getting this each time ive been working with the last 121b build,

happens approx after about 1 hour. requires restart of Chrome to fix.

there is a "Failed to Initialise WebGL context error" in the console.

just wondering if any of you guys getting ???

edit

ps maybe something to do with working off line, I was trying to sneak a hour after work at the office and I cant use internet here on the game dev pc.

This has been happening even before 120/121 etc. In some strange cases webgl just crashes in preview(results black screen) and then editor view is blank, even tought you can still click and select objects. Ordinary it happens when doing some tests with huge amount of sprites.

You can get similar crash in shadertoy.com when viewing some examples there.

It has never happened with just 1 preview test, but over time while you have done like 5-6+ test. So there could be some kind of leak.

I got different console error when it has happened. "WebGL: "Context_Lost_Webgl: loseContext: context lost"

Oh good , Im not alone.....

yes you describe it exactly the same, black screen on preview, layouts become blank but Construct remains functional, it dosent crash, you can still mess with events , you can even save and there is no corruption of file. But you need to restart Chrome to get the layout editor back and to be able to preview again.

I haven’t been able to deliberately replicate it by repeatedly previewing my project, I dont see any jump in system or GPU memory or CPU so I dont know. My project is definily pushing a fair few sprites around but nothing it hasn’t been doing for a long time and hasn’t happened before

All I can say is it just happens after clicking preview but only after some time usually an hour or two .... which isnt very helpful for bug reporting,....hmmmmmm

HI Ashley

Its happening on two very different machines running different versions of chrome, surface pro with integrated gfx and a HP Zbook 3D workstation with Quadro gfx so i dont think it is specifically related to a particular gfx card / driver combo failing.

also it appears to be walled within the chrome environment when using construct editing and previewing , and everything outside chrome gfx wise is fine.

also it can be resolved by restarting chrome, so may be a chrome issue, but it dosent resolve by restarting unless construct can communicate with construct servers for some sort of webgl validation. So some part of the issue is related to being off line.

Im not using any physics in my project but yes it does feel like some sort gpu mem leak, I will try to have a thorough look at how gpu is behaving tonight.
