Having rebooted into a fresh Plasma Wayland session, running nvtop in one Konsole window, I opened another Konsole window and tried moving and resizing it. The new Konsole window opened tiled to the right half of the screen (I rebooted from a Konsole tiled exactly there). Moving it around the screen didn't affect kwin_wayland VRAM usage. Resizing it, though, made kwin_wayland quickly reach 10% of VRAM usage (2.4GB on RTX 4090), and stay pegged at that level regardless of any further window shape or position changes. I thought, oh well, resizing Konsole does make kwin_wayland hog VRAM, as reported by Kelvie Wong above, and was about to reboot. I invoked the keyboard shortcut to tile that Konsole window back to the right half of the screen where it opened, and that made kwin_wayland release all that VRAM back to under 1% level, to my great surprise. It appears, that restoring Konsole window size and position back to their initial states makes kwin_wayland release that 10% VRAM it allocated during moving around and resizing that window. Let me know what other information I could collect to narrow down the root cause of the issue. -- You are receiving this mail because: You are watching all bug changes.
