When I switching to sleep mode, Plasma is locked after resume. Example of problem : → I close panel (of my laptop). → Computer switch to sleep mode → I reopen panel, and I continue to see all apps opened for several seconds → Lockscreen appear in this moment. ############ System: Host: laptop02 Kernel: 4.15.0-32-generic x86_64 (64 bit) Desktop: KDE Plasma 5.13.4 Distro: neon 16.04 xenial Machine: System: TOSHIBA product: SATELLITE C660 v: PSC1QE-02V00FFR Mobo: TOSHIBA model: PWWHA v: 1.00 Bios: TOSHIBA v: 1.10 date: 07/11/2011 CPU: Dual core Intel Core i3-2310M (-HT-MCP-) cache: 3072 KB clock speeds: max: 2100 MHz 1: 1108 MHz 2: 929 MHz 3: 1104 MHz 4: 1051 MHz Graphics: Card: NVIDIA GT218M [GeForce 315M] Display Server: X.Org 1.18.4 driver: nvidia Resolution: 1366x768@60.00hz GLX Renderer: GeForce 315M/PCIe/SSE2 GLX Version: 3.3.0 NVIDIA 340.107 Audio: Card-1 NVIDIA High Definition Audio Controller driver: snd_hda_intel Card-2 Intel 6 Series/C200 Series Family High Definition Audio Controller driver: snd_hda_intel Sound: Advanced Linux Sound Architecture v: k4.15.0-32-generic Network: Card-1: Realtek RTL8101/2/6E PCI Express Fast/Gigabit Ethernet controller driver: r8169 IF: enp2s0 state: down mac: b8:************** Card-2: Realtek RTL8188CE 802.11b/g/n WiFi Adapter driver: rtl8192ce IF: wlp3s0 state: up mac: 7c:4f:b5:f6:14:4a Drives: HDD Total Size: 750.2GB (48.6% used) ID-1: /dev/sda model: WDC_WD7500BPVT size: 750.2GB Partition: ID-1: / size: 92G used: 16G (19%) fs: ext4 dev: /dev/sda1 ID-2: /home size: 596G used: 319G (54%) fs: xfs dev: /dev/sda5 ID-3: swap-1 size: 5.00GB used: 0.59GB (12%) fs: swap dev: /dev/sda6 RAID: No RAID devices: /proc/mdstat, md_mod kernel module present Sensors: System Temperatures: cpu: 48.0C mobo: N/A gpu: 49C Fan Speeds (in rpm): cpu: N/A Info: Processes: 254 Uptime: 2 days Memory: 4747.0/7955.2MB Client: Shell (bash) inxi: 2.2.35
I experience the same issue with the difference that I only see my desktop for a fraction of a second before the Lockscreen appears. I guess presenting the lockscreen is the correct behaviour, however the user's desktop should not be exposed. ############ Kubuntu 18.04.1 64bit + mainline kernel 4.17.19 + NVMe SSD

Same issue with a Desktop, tends to happen when sleeping for longer, I'll see the desktop for a second or two before lockscreen is shown. One time I've even been able to bypass the lockscreen (resumed and was able to use the computer without entering my password) which makes me think this is a security concert, however I haven't been able to reproduce it.
I can't see anything like that after waking up from suspend on Plasma 6.2.5! On Debian 13 (testing repository). Maybe it was fixed.
Still happens for me with 6.3.0 every time i wake up so definitely not fixed.
