SUMMARY STEPS TO REPRODUCE 1. On a laptop, open the Battery and Brightness applet. 2. Use your touchpad to move the slider to 100%. OBSERVED RESULT While moving the slider with the cursor you can only go to 99%. You can reach 100% if you scroll on the slider instead. EXPECTED RESULT The user should be able to drag the slider to 100%.

Works for me. What font and font size are you using? And does this affect the sliders in the Volume applet too, or just the Battery & Brightness applet?

Screen is at 1x scale with a 1366x768 resolution. The only modification I made to Plasma was shrinking the default panel to 28px. All other sliders work as intended, it's only the brightness slider that doesn't go all the way to 100%. One thing I noticed is that if I click on the slider and move it with the arrow keys I can go to 100%, but if I press left to go back to 99% it instead jumps straight to 98%, if I keep pressing left it moves by 1% as it should. I also tried moving the panel just in case it was caused by a lack of drag space for the cursor but the same happens. It's a very insignificant bug, so don't worry much about it :P
How very strange.
(In reply to Nate Graham from comment #3) > How very strange. Very strange indeed. I asked on Reddit and apparently no one could reproduce the bug, however, I booted up the Neon live image I used to install and I the problem is there. The iso is neon-user-20210311-0944.iso so it's pretty recent. :|
FWIW I have everything built from git master on openSUSE Tumbleweed, so I don't think it's a matter of recency. I wonder if it could be somehow Neon-specific.
Yeah, I think you can close this bug. I used the same Neon image on another laptop and it worked fine there. It must be some kind of driver problem. It's really odd it would only happen when dragging with the cursor but since it only happens on this machine it most likely isn't a bug in Plasma. Thanks a lot. :)
Okay. :)
