Created attachment 165018 [details] Krunner open with the typed text misaligned with the predicted text. Krunner seems to predict what you will type based on previously entered searches. These show up semi-opaque, while the text you type is opaque. When the ("General") font size is changed in System Settings, the prediction text in Krunner does not line up with the typed text. Neither font changes size, but the typed text is always vertically centred while the prediction text is aligned with the top of the search box. The icons to the left and right within the search box change size (i.e. change the vertical size of the box) and this seems to be causing the typed & predicted text be misaligned. Both typed and predicted text should be vertically centred, and either the both texts should reflect the ("General") font size set in System Settings, or else the other Krunner elements should not scale up / down when the font size is changed.

Similarly, with Plasma 6.0.3 on Arch, searching seems to be case-independent, but if the case does not follow the case of the previously searched string, then the prediction displays in a different case to the string currently typed. E.g when entering a search "KONS" the prediction in the background might be "konsole" which means the different cases overlap each other and it looks broken and is hard to read. I would say the only prediction text that should be shown are the letters after the end of the typed text, i.e. for a search string "KONS" the prediction should add only "ole" to the end. Then, if both typed text and prediction are part of the same styling (apart from their text colours) then perhaps the original bug report would be resolved too...
Created attachment 172432 [details] KRunner with Noto Sans in sizes: 10pt, 8pt, 6pt. I can reproduce the problem with fonts "small enough", even after restarting KRunner. In the attached image the 10pt font renders OK, while 8 and 6 trigger the bug.
