Well that's weird. Never seen that before. Probably a width calculation rounding error somewhere that only happens when using certain fractional scale factors.

Not only 162,5% is affected but also simple integer 200% scaling as I mentioned in my dup bug report.

I use 200% scale myself and FWIW, have never seen this with either 10pt Noto Sans or 11pt Noto Sans, on either X11 or Wayland.

200% scale, 10pt Noto Sans and to go sure it's not a caching issue, I have emptied `~/.cache/` and rebooted, but the issue still persists. 
However, I can reproduce it with any scaling, e.g. 100% or 150%. Thus it doesn't seem to be related to _a_ scaling factor.

Also cannot remember to have ever seen it on 5.27.4 or prior, therefore I have added the regression keyword.

I cannot reproduce the issue when having a 200% scaling and Noto Sans <= 5pt, but for Noto Sans >= 6 pt.
My comments only regard the Wayland session.

This is caused by https://invent.kde.org/plasma/plasma-workspace/-/merge_requests/2795

With the translations fixed the string now is e.g. "110 %" while before the untranslated string was "110%" (note the space between the number and percent). Whether you are affected by this therefore depends on your language

In case the translation has both a space in the actual string and the fixed "maximum string" "100 %" (which is a fair assumption), it might be an issue with `TextMetrics.width`, which has shown some problems in the past, specially when measuring whitespaces (example: https://bugs.kde.org/show_bug.cgi?id=421973 and https://invent.kde.org/system/dolphin/-/merge_requests/22). Usually `advanceWidth` provides a better value

OSD: Fix size calculation for progress value

Use a common function for formatting the percent, so placeholder 100% label will
use the exact formatting used by the label next to the progress bar.

Also use font advanceWidth, which is the appropriate means of calculating the
bounding box of text in this case. Also ceil it to avoid subpixel alignment.

And to be absolutely sure disable word wrapping.
