Webgl renderer: context lost

[tisilent]

(Toggle Developer Tools)

after completion yarn run test-api.
When scrolling through the results in Terminal, the screen is black and Terminal is white But the selected line shows the content. It works normally after standby startup.

@tisilent doesn't the browser close after yarn run test-api? But confused how you get to the console

[tisilent]

Running in vs code.

@tisilent You can also add an await new Promise(r => setTimeout(r, some_high_value)) in your test case, which gives you time to navigate to the console of the test browser instances of playwright.

Edit: No clue if setting a breakpoint would work in playwright, kinda never tested that...

@Tyriar @jerch I have found the reason.
graphics drivers! 😟

The monitor driver igfx has stopped responding and has successfully recovered.

graphics drivers! 😟

Oh dear, not again. Not sure if you want to get again into the chromium graphics debugging nightmare, to narrow things down:

• Does this also happen with yarn test-api-firefox?
• You can also test with an older playwright version (would ship older chromium version).

On a sidenote: Idk if you have a faulty driver setup or just edgy hardware the chromium devs did not test, but it seems to be much more of an issue since chromium v108+.

I have found the reason this time. The probability of this problem occurring should be very, very low.
And the 'webglcontextrestored' event was successfully executed. It was restored, but it seems that_ RequestRedrawViewport did not effect. Looking back now. 🤔

[tisilent]

It appeared today, and the term was initially a fork icon, then returned to normal. webglcontextrestored take effect。

[tisilent]

@Tyriar This may not be a problem. 😬
I think we can close the issue.
