Tried baking down to kernel -42, which is much older but I'm still seeing the problem. Maybe the issue is not with the kernel, it just happened to occur at the same time :-(

Parts of the UI are replaces with black boxes. Resizing the window causes it to redraw but if I switch back to the original size then it goes back to black. I noticed it on 5.4.0-47 and backed down to 5.4.0-45 but still see the same. Looks like 5.4.0-45 was only released a few days before 5.4.0-47 so maybe I didn't reboot in that time. Those are the only upgrades I can see in the right timeframe. I had a look in dmesg and saw some warnings; not sure if they're related: [ 59.251347] ------------[ cut here ]------------ [ 59.251357] WARNING: CPU: 6 PID: 4533 at drivers/media/v4l2-core/v4l2-ioctl.c:1069 v4l_querycap+0x8f/0xa0 [videodev] [ 59.251358] Modules linked in: msr nf_conntrack_netlink xfrm_user xfrm_algo xt_addrtype br_netfilter rfcomm ccm typec_displayport cmac algif_hash algif_skcipher af_alg xt_CHECKSUM xt_MASQUERADE xt_conntrack ipt_REJECT nf_reject_ipv4 xt_tcpudp ip6table_mangle ip6table_nat iptable_mangle iptable_nat nf_nat nf_conntrack nf_defrag_ipv6 nf_defrag_ipv4 nf_tables nfnetlink ip6table_filter ip6_tables iptable_filter bpfilter bridge stp llc aufs overlay bnep binfmt_misc nls_iso8859_1 btusb btrtl btbcm btintel snd_usb_audio bluetooth snd_usbmidi_lib ecdh_generic ecc uvcvideo videobuf2_vmalloc videobuf2_memops videobuf2_v4l2 videobuf2_common dell_rbtn snd_sof_pci snd_sof_intel_hda_common snd_soc_hdac_hda snd_sof_intel_hda snd_sof_intel_byt snd_sof_intel_ipc snd_sof snd_sof_xtensa_dsp mei_hdcp snd_hda_ext_core snd_hda_codec_hdmi snd_soc_acpi_intel_match snd_soc_acpi intel_rapl_msr snd_soc_core snd_compress ac97_bus snd_hda_codec_realtek snd_pcm_dmaengine x86_pkg_temp_thermal intel_powerclamp [ 59.251391] snd_hda_codec_generic coretemp snd_hda_intel snd_intel_dspcfg snd_hda_codec snd_hda_core snd_hwdep snd_pcm dell_laptop ledtrig_audio snd_seq_midi snd_seq_midi_event kvm_intel kvm iwlmvm snd_rawmidi rapl mac80211 snd_seq dell_wmi dell_smbios input_leds dcdbas intel_cstate libarc4 snd_seq_device serio_raw snd_timer iwlwifi snd dell_wmi_descriptor intel_wmi_thunderbolt wmi_bmof rtsx_pci_ms mxm_wmi cfg80211 memstick soundcore mei_me hid_multitouch mei joydev processor_thermal_device intel_rapl_common intel_soc_dts_iosf intel_pch_thermal ucsi_acpi typec_ucsi typec int3403_thermal int340x_thermal_zone dell_smo8800 intel_hid int3400_thermal acpi_thermal_rel mac_hid acpi_pad sparse_keymap nvidia_uvm(OE) sch_fq_codel v4l2loopback(OE) videodev mc dell_smm_hwmon parport_pc nfsd ppdev auth_rpcgss nfs_acl lockd lp parport grace sunrpc ip_tables x_tables autofs4 btrfs zstd_compress dm_crypt raid10 raid456 async_raid6_recov async_memcpy async_pq async_xor async_tx xor raid6_pq libcrc32c [ 59.251428] raid1 raid0 multipath linear wacom usbhid hid_generic nvidia_drm(POE) nvidia_modeset(POE) crct10dif_pclmul crc32_pclmul ghash_clmulni_intel nvidia(POE) rtsx_pci_sdmmc i915 aesni_intel crypto_simd cryptd i2c_algo_bit glue_helper drm_kms_helper nvme syscopyarea sysfillrect sysimgblt fb_sys_fops nvme_core i2c_i801 rtsx_pci intel_lpss_pci drm ahci intel_lpss ipmi_devintf idma64 libahci ipmi_msghandler virt_dma i2c_hid hid video pinctrl_cannonlake wmi pinctrl_intel [ 59.251451] CPU: 6 PID: 4533 Comm: chrome Tainted: P U W OE 5.4.0-45-generic #49-Ubuntu [ 59.251452] Hardware name: Dell Inc.
