Vertically stretched cursors on buster desktop

[Malte Forkel <malte.forkel@berlin.de>]

Hi,

I have installed buster an an old FSC Primergy Econel 50. The GNOME
desktop works, I can open applications without freezing the machine (as
opposed to stretch), but all cursors are stretched by a factor of four.
Between each line of the cursor image, there are three background lines.

The kernel is 4.18.0-1-686-pae, the X Server is 1.20.1, it uses the KMS
driver i915, version 1.6.0 20180514. The graphics controller is
identified by lspci as

00:02.0 VGA compatible controller: Intel Corporation E7221 Integrated
Graphics Controller (rev 04) (prog-if 00 [VGA controller])
        Subsystem: Fujitsu Technology Solutions E7221 Integrated
Graphics Controller
        Flags: bus master, fast devsel, latency 0, IRQ 11
        Memory at f0000000 (32-bit, non-prefetchable) [size=512K]
        I/O ports at 1000 [size=8]
        Memory at e0000000 (32-bit, prefetchable) [size=256M]
        Memory at f0080000 (32-bit, non-prefetchable) [size=256K]
        [virtual] Expansion ROM at 000c0000 [disabled] [size=128K]
        Capabilities: [d0] Power Management version 2
        Kernel modules: i915

What should I do? If this is a bug, I wouldn't even know which package
to file a bug report against.

Thanks,
Malte
