oxal...@pm.me changed: What |Removed |Added ---------------------------------------------------------------------------- Resolution|WORKSFORME |--- Status|RESOLVED |REPORTED --- Comment #2 from oxal...@pm.me --- I can reproduce it with 22.08.1, which is also current master, under sway window manager (wayland). SOFTWARE/OS VERSIONS sway version: both 1.7 and current master cffb006feba52c318e66f73c3463032fa76782dc reproduce kolourpaint version: 22.08.1 Qt version: 5.15.5 OS: NixOS unstable CPU/GPU: AMD Ryzen 7 5700G with integrated GPU RAM: 16GiB ADDITIONAL INFORMATION 1. 100% scale or 200% scale both work flawlessly. Only 125% scale causes significant redraw lag (500ms to 1s delay) even when selecting "Brush" tool and moving the cursor fast on the canvas, no need to press mouse button. 2. There are also many lines of "QWaylandShmBuffer: mmap failed (Invalid argument)" printed in console. -- You are receiving this mail because: You are watching all bug changes.
