Created attachment 160022 [details] Screenshot with spectacle SUMMARY I have 3 monitors set up (see https://ibb.co/G9P8WQh). I am maximing an glfw application and on the right most monitor is one pixel par on the side still free. Interstingly it stays white when the cursor moves (see the attache screenshot). STEPS TO REPRODUCE 1. Grab 3 monitors and an nvidia gpu 2. Open minosoft https://gitlab.bixilon.de/bixilon/minosoft, go into rendering and then maximize the window OBSERVED RESULT See the one pixel wide border on the right between both monitors. EXPECTED RESULT No border SOFTWARE/OS VERSIONS Operating System: siduction 22.1.0 KDE Plasma Version: 5.27.5 KDE Frameworks Version: 5.107.0 Qt Version: 5.15.8 Kernel Version: 6.3.10-1-siduction-amd64 (64-bit) Graphics Platform: Wayland Processors: 16 × AMD Ryzen 7 3700X 8-Core Processor Memory: 31.3 GiB of RAM Graphics Processor: NVIDIA GeForce GTX 1060 6GB/PCIe/SSE2 Product Name: X370 Killer SLI ADDITIONAL INFORMATION I do mix scaling on wayland and it does not appear when all monitors are on 100%. The screenshot shows minosoft on the left, the pixel bar in the center and my wallpaper on the right
It actually also happens on the right most screen with chromium. That is the reason why I sometimes click on other windows (that are below chromium) when going in the top right corner in order to close it and it also happens sometimes on my laptop with a single monitor at 100% scale. Just to mention: I do not use window frames.
