[hoyosjs]

This started showing up a lot in rolling builds for ARM64 windows on CoreCLR https://runfo.azurewebsites.net/search/tests/?q=started%3A%7E7+definition%3Aruntime+name%3ASystem.Drawing.Tests.GraphicsTests

[hoyosjs]

Also has a pretty odd distribution

[danmoseley]

How do you get that graph @hoyosjs ? Is it a runfo thing?

[hoyosjs]

This one is from AzDO analytics view. Ones with more detail can give extracted from Listo Kusto, but for simple high hit rate tests I check AzDO from time to time.

[danmoseley]

Listo?

[hoyosjs]

Kusto* (autocorrect in Spanish+English does some interesting guesses)
