All builds I've done were in clean chroots, so starting from scratch with just git source, with no interference from other builds. Also later in #8, I show that --disable-glusterfs doesn't work because some part of the build looks for the .so that was never built. Luckily, be812c0 was easy enough to just manually revert on top of 4.1.0. And, good news. (I hope!) 4.1.0 with be812c0 manually reverted on top of it prevents the bug, even WITHOUT "max_outputs=3D1". -- = You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1843151 Title: Regression: QEMU 4.1.0 qxl and KMS resoluiton only 4x10 Status in QEMU: New Bug description: Host is Arch Linux. linux 5.2.13, qemu 4.1.0. virt-viewer 8.0. Guest is Arch Linux Sept 2019 ISO. linux 5.2.11. Have replicated this both on a system using amdgpu and one using integrated ASPEED graphics. Downgrading from 4.1.0 to 4.0.0 works as usual, see: https://www.youtube.com/watch?v=3DNyMdcYwOCvY Going back to 4.1.0 reproduces, see: https://www.youtube.com/watch?v=3DH3nGG2Mk6i0 4.1.0 displays fine until KMS kicks in. Using 4.1.0 with virtio-vga doesn't cause this. To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1843151/+subscriptions
