Transparency/blur issue with context menu

[subhasutra]

Opening up a few applications and right clicking on them is causing some visual issue. So far I've checked with dolphin and konsole. This is how the context menu looks while hovering over it.

The hovered options have a different effect. This however only happens on first time right clicking, afterwards this doesn't occur and it behaves normally.

Wayland?

Can you tell me what color theme you're using? It would make it a bit easier to try to find the problem

[subhasutra]

I am using a custom colour scheme, however the issue persists with breeze light and dark as well. Also the transparency within lightly is set to 70% for menus. And yes I'm using wayland.

[christiantosta]

Menus 70% opaque is so low for me (I use 90%), but it's not the cause of problem. Works fine here with this amount.

Enablind the Kwin effects "Blur" and "Background Contrast" resolves the issue for you? Kwin effect "Transparency" appears to have some conflicts with Lightly.

this is not just a lightly issue, this also happens with blurry kvantum themes like layan

Works for me with Vinyl and Lightly. But with Lightly, the top rounded borders shows me a dark blue corner.

I can only see the wierd corner thing, but it's not blue for me, just blurred. But it seems that transparency needs a lot of work.

[subhasutra]

It's definitely a transparency issue, happens even without blur. Images for comparison.

First time right clicking to open context menu:

Next time onwards:

Can confirm, seeing it with kvantum as well.

Perhaps related with mesa or video drivers?

It could be, I'm running on amd, and I have no idea how to replicate this bug. Does this bug get away with a reboot or is it there every time you right click first after opening something?

May want to check for this "[AdaptiveTransparency]" settings in the theme being used and disable it.

I think there is a mention of the problem in kvantum's latest release, as the version 1.1.3 fixes the same problem. The release note says

Qt 6.8.0 has a regression that randomly creates artifacts in translucent windows under Wayland. A workaround has been added for it, such that the windows/menus/tooltips which are made translucent by Kvantum are not affected by it.

I don't think mesa should be the issue, as downgrading didn't help.

It is persistent, happens every time I open a new window.

This didn't help.
