1. Please describe the problem: Updated Fedora 30 yesterday, 8-6-2019. New kernel 5.2.5-200.fc30.x86_64 boots OK. Graphics within windows of apps such as Thunderbird get scrambled. It appears some windows work OK for example keepass appears to work cleanly which uses different libraries. I don't know how to check what other updates came in yesterday, there were more than just the kernel. If I can check the update history??? I can update this report with what else was changed. This is not the same as the raven_dmcu.bin firmware issue reported in https://bugs.freedesktop.org/show_bug.cgi?id=109206 Booting on previous version of kernel all works well. Previous Kernel is kernel="/boot/vmlinuz-5.1.20-300.fc30.x86_64" args="ro resume=/dev/mapper/fedora-swap rd.lvm.lv=fedora/root rd.lvm.lv=fedora/swap rhgb quiet idle=nomwait" root="/dev/mapper/fedora-root" initrd="/boot/initramfs-5.1.20-300.fc30.x86_64.img" title="Fedora (5.1.20-300.fc30.x86_64) 30 (Thirty)" id="37abfd967dfe4ee5a8e8b5abfc9e098b-5.1.20-300.fc30.x86_64" 2. What is the Version-Release number of the kernel: kernel="/boot/vmlinuz-5.2.5-200.fc30.x86_64" args="ro resume=/dev/mapper/fedora-swap rd.lvm.lv=fedora/root rd.lvm.lv=fedora/swap rhgb quiet idle=nomwait" root="/dev/mapper/fedora-root" initrd="/boot/initramfs-5.2.5-200.fc30.x86_64.img" title="Fedora (5.2.5-200.fc30.x86_64) 30 (Thirty)" id="37abfd967dfe4ee5a8e8b5abfc9e098b-5.2.5-200.fc30.x86_64" 3. Did it work previously in Fedora? If so, what kernel version did the issue *first* appear? Old kernels are available for download at https://koji.fedoraproject.org/koji/packageinfo?packageID=8 : Yes as noted above 4. Can you reproduce this issue? If so, please provide the steps to reproduce the issue below: Yes, every time. 5. Does this problem occur with the latest Rawhide kernel? To install the Rawhide kernel, run ``sudo dnf install fedora-repos-rawhide`` followed by ``sudo dnf update --enablerepo=rawhide kernel``: Have not tried this 6. Are you running any modules that not shipped with directly Fedora's kernel?: No 7. Please attach the kernel logs. You can get the complete kernel log for a boot with ``journalctl --no-hostname -k > dmesg.txt``. If the issue occurred on a previous boot, use the journalctl ``-b`` flag. Will attache if I can get after a boot back to problem kernel

Problem persists in 5.2.6 downloaded today.
Created attachment 1602256 [details] Example dmesg Nothing obvious to me. Latest BIOS here has been working fine before jump to kernel 5.2. Please advize on any data needed.
Problem persists in kernel-5.2.7, ThinkPad E585 (AMD Ryzen 7 2700U with Radeon Vega Mobile Gfx).
Problem doesn't seem to affect kernel-5.0.9-301.fc30.x86_64, but higher versions only.
Problem still persists with kernel-5.2.9-200.fc30.x86_64. Last usable kernel is kernel-5.1.20-300.fc30.x86_64. Anyone have any suggestions?
I believe I've had the same issue on my Thinkpad A485. Kernel 5.1.12 worked fine, Using 5.2.8 or 5.2.9 resulted in visual corruption and eventually a hard freeze. Before creating a bug report I wanted to ensure that I had the latest updates, including the laptop's BIOS. So I updated all packages - which didn't solve the issue, then I updated the BIOS from 1.11 to 1.24 and the problem seems to be gone. I am not sure whether the fix was the BIOS update itself, or the reset of the BIOS settings. I did toy around with the BIOS to prevent the random freeze issue that's plaguing the A485s. I'm going to have a look around the BIOS and see if some setting can recreate the issue.
With the kernel-5.2.11-200.fc30.x86_64 update that came in today, this bug appears to be fixed. Al stable. Closing
