Created attachment 159293 [details] Video of the timer counting down too quickly SUMMARY The timer does not keep time with the system clock, and counts down much too quickly STEPS TO REPRODUCE 1. Add a new timer widget to the panel 2. Start a timer OBSERVED RESULT The timer counts down approximately 2.5 seconds per second. EXPECTED RESULT The timer should count down exactly 1 second per second. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Debian 12 / Linux 6.1.0-7-amd64 (64-bit) (available in About System) KDE Plasma Version: 5.27.2 KDE Frameworks Version: 5.103.0 Qt Version: 5.15.8 ADDITIONAL INFORMATION Please see attached video for proof.
Are you using Nvidia?
I'm not using Nvidia; my CPU is a AMD Ryzen 7 3800X and the GPU is a AMD Radeon R9 380. I'm using the amdgpu graphics driver.
Out of curiosity are you using a 144hz refresh screen? If so, this is Bug 419421, which is fixed in Plasma 6. See the bug report for a workaround on Plasma 5.

Ok, thanks. Is it only the Timer widget, or do other times things in Plasma exhibit the same issue? For example do notifications time out 2.5x as fast?

For example do notifications time out 2.5x as fast? Now that you mention it, I've just checked the settings and it seems that notifications do time out much too quickly as well - I tested by setting the notification timeout to 20 seconds, made a notification appear, and it timed out in about 8 seconds. I also tried changing the Plasma animation speed to the slowest setting to rule it out but it had no effect. I've also noticed that the issue is a slightly inconsistent - I've seen the timer work correctly once or twice, I think (?) shortly after starting my computer. It inevitably starts misbehaving at some point during the day, and then never works again until a restart, and usually not even then.
Ok, then it does sound like you're experiencing the same symptoms as Bug 419421, despite not having the same triggering hardware. Nonetheless, the Qt6 fix should work for you as well.
