Created attachment 163941 [details] screenshot of the blurry item SUMMARY The hovered item in the clipboard applet is blurry STEPS TO REPRODUCE 1. Copy multiple strings to the clipboard 2. Open the applet and move the mouse over one of the items 3. The hovered item (the content and all the icons) is blurry OBSERVED RESULT The hovered item is blurry EXPECTED RESULT The hovered item should not be blurry SOFTWARE/OS VERSIONS Linux/KDE Plasma: ArchLinux KDE Plasma Version: 5.90.0 KDE Frameworks Version: 5.246.0 Qt Version: 6.6.1 ADDITIONAL INFORMATION

(In reply to Fushan Wen from comment #1) > wayland? Yes
Cannot reproduce on Wayland at 200% scale. What scale factor are you using?
(In reply to Nate Graham from comment #3) > Cannot reproduce on Wayland at 200% scale. What scale factor are you using? I am at 100%. I can also not reproduce at 200%. It seems to happen for every scale factor from 150% and below although below 100% it is difficult to see for sure
Can reproduce at 100% scale: the text shifts over to the left slightly when hovered. I'm guessing it's on a fractional pixel location, which causes the blurriness.

Still experience this issue in Plasma 6.0.1 Hovering under the clipboard history applet causes text to become blurred. Scale factor: 1.5 KDE Plasma Version: 6.0.1 KDE Frameworks Version: 6.0.0 Qt Version: 6.6.2 Graphics Platform: Wayland
Also, I've noticed that all controls inside the systray have graphics glitches when using fractional scale. 1. Font has glitches (artifacts, half-rendered characters, etc.) 2. Control slides are blurred. 3. Checkbox circles are blurred + dot inside the circle with artifacts (because of upscale?). 4. Clipboard history text all with artifacts 5. Network monitor also with control and fonts problems(it is dancing now :)) Also, Spectacle makes blurred screenshots under Wayland, so I've attached one screenshot from an X11 session(which also now has artifacts in QML controls inside the systray; KDE 5 didn't have this in the X11 session at all) Please find archive in attachments, there is screenshots and screen cast of dancing fonts.

Let's use this bug report only for blurry text; blurry icons constitute a separate thing that's less fixable than blurry text. I can reproduce the issue at 225% scale. It's subtle and hard to notice, but clearly there. I think it's a pixel-misalignment issue as the text visible moves a bit when hovered.
The OpacityMask appears to be causing this. If I remove it, the issue disappears. Could be an inherent issue with masking a label, it could be a pixel misalignment between the original label and the masked version that we substitute for it on the hovered item.

That's not the issue; this specific source of blurriness is caused by the opacity mask.
Yes, sorry. It's about the glitched and dancing font in P.5
