[Wesnoth-bugs] [bug #23607] editor: severe FPS drop in map generation settings
URL: http://gna.org/bugs/?23607 Summary: editor: severe FPS drop in map generation settings Project: Battle for Wesnoth Submitted by: matthiaskrgr Submitted on: Sun 24 May 2015 12:41:27 AM UTC Category: Bug Severity: 2 - Minor Priority: 5 - Normal Item Group: Editor Status: None Privacy: Public Assigned to: None Originator Email: Open/Closed: Open Discussion Lock: Any Release: git Operating System: linux ___ Details: open the editor, then go Map - generate Map. Fps is reported to be 50, and it feels fine. But when I now hit the Settings button, fps is reported to be 90 however I'd estimate it is rather 10-15ish. The bottom text-line which tells the currently selected terrain type gets a bit darker which makes me assume that things are rendered on top of each other in a strange way. @ 464b9a50e9047e46a71195e6a3e544c226bf9c6e ___ Reply to this item at: http://gna.org/bugs/?23607 ___ Message sent via/by Gna! http://gna.org/ ___ Wesnoth-bugs mailing list Wesnoth-bugs@gna.org https://mail.gna.org/listinfo/wesnoth-bugs
