You need an Intel graphics card to reproduce this bug.

Yeah, the problem is probably that the GL_FRAMEBUFFER_ATTACHMENT_COLOR_ENCODING is GL_LINEAR with the Intel driver, and that means that the final conversion from linear to sRGB is not happening in the upscaleRenderToScreen() pass.

We should probably not use sRGB textures when the driver reports that the framebuffer color encoding is linear.

However, it might also be a bug in the driver that it doesn't pick an sRGB format for the default framebuffer. We should discuss that with the Intel developers, but I would appreciate it if someone who has an Intel GPU could investigate this a bit further first. At the very least confirm that glGetFramebufferAttachmentParameteriv() in fact returns GL_LINEAR.

https://bugs.kde.org/show_bug.cgi?id=408790 I am not the only one with issue, the issue was reported also from Latte users that probably use Intel driver

My transparent Konsole is also noticeably darker now, but it actually seems to me like the background color of the Konsole color scheme got somehow changed. It doesn't match the color in the regular color scheme anymore.

I am using Plasma 5.16, this patch probably can create TOO DARKISH results so the natural part of the commit is not valid and probably breaks users experience also:

I really like the idea...
