Bug ID: 468440 Summary: Global Application shortcuts are slower than they could be Classification: I don't know Product: kde Version: unspecified Platform: Other OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: general Assignee: unassigned-b...@kde.org Reporter: aleksey.kla...@gmail.com Target Milestone: --- SUMMARY Global Application shortcuts (like `M+.` for emojier) add about 100ms delay in comparison to pinning the app in taskbar and using `Win+number` shortcut. That is, launching emojier with `M+.` is noticeably slower for me than pinning it and launching a new instance via `Win+1` STEPS TO REPRODUCE The delay is visible with a nacked eye, especially if you compare two kinds of shortcuts (xclock is a guinea pig). But I also confirmd that with time measurments using these two scripts click.sh logs current time and uses ydotool to send `F4` shortcut ``` #!/bin/sh date +%s.%N >> "/home/matklad/tmp/log.txt" ydotool key 62:1 62:0 ``` clock.sh logs current time ``` #!/bin/sh date +%s.%N >> "/home/matklad/tmp/log.txt" echo "\n" >> "/home/matklad/tmp/log.txt" ``` If I bind F4 to global script shorcturt ``` [clock.sh.desktop] _k_friendly_name=clock.sh _launch=F4,none,/home/matklad/tmp/clock.sh ``` the result looks like this ``` 1681339791.367891270 1681339791.488687436 \n 1681339792.845658459 1681339792.964949291 \n 1681339793.893609292 1681339794.015043447 ``` That's about 120ms of delay between click.sh and clock.sh If I find F4 to task manager ``` activate task manager entry 1 ``` the result looks like this ``` 1681340227.988185176 1681340228.001887438 \n 1681340229.466190483 1681340229.482717773 \n 1681340230.419816890 1681340230.437328642 ``` about 20ms of delay, 100ms faster than the global shortcut SOFTWARE/OS VERSIONS Operating System: NixOS 23.05 KDE Plasma Version: 5.27.4 KDE Frameworks Version: 5.105.0 Qt Version: 5.15.8 Kernel Version: 6.2.10 (64-bit) Graphics Platform: Wayland Processors: 20 × 12th Gen Intel® Core™ i7-12700H Memory: 62.5 GiB of RAM Graphics Processor: Mesa Intel® Graphics Related issue: https://bugs.kde.org/show_bug.cgi?id=468328 -- You are receiving this mail because: You are watching all bug changes.
