Black rectangles in Firefox ater upgrade to 5.21.15

This is my first bug report. Please let me know if I did something wrong.

After upgrading from 5.21.14 to 5.21.15 my Firefox shows random black rectangles. (photo attached)
They appear and disappear randomly while scrolling.
They disappear when Firefox window looses focus.
I recognised a few of them in Thunderbird. (But not as bad as in Firefox!)

I tried older versions of Firefox but I had the same issues.
Disabling hardware acceleration in Firefox changed nothing.

After downgrading to 5.21.14 everything works as usual.

I am using Arch Linux on a Lenovo x230t with an Intel HD4000.

Please let me know if I can do anything.

5.21.14 and 5.21.15 aren't kernel versions .... Please clarify what exactly you've upgrade that broke things.

What he means is 2.21.14, https://bugs.freedesktop.org/show_bug.cgi?id=68410

Fascinating bug. Seems like I need a w/a for an upset GPU.

Ok, looks like it's not a kernel bug then, so better tracked in the fdo bugzilla. Max, thanks for your report and please reopen if the fdo bug isn't the same as you have (but I think that's unlikely).
