Committed on 18/01/2024 at 15:15. Pushed by vladz into branch 'master'. opengl: Correct transformation order in GLTexture::render() First, the texture-to-buffer transform has to be applied, then the y axis should be flipped. Doing it vice versa changes the winding order of rotation transforms. Also the screenshot plugin uses incorrect render transform. Since convertFromGLImage() undoes the render target's transform, the color space transformation pass should use the same transform, not the inverted one.

New screenshot with reproducible problem.
SUMMARY
Blur effect texture flipped on 180 degrees.
The behavior of regular applications has been fixed (for example, the Konsole in the screenshot). However, plasma widgets still display blur incorrectly. ("New screenshot with reproducible problem")

I cannot reproduce the issue. Try reducing blur strength and also disabling the background contrast effect to have a clearer view of the background. (In reply to Vlad Zahorodnii from comment #6) > I cannot reproduce the issue. Try reducing blur strength and also disabling > the background contrast effect to have a clearer view of the background. How can I disable blur on the plasma panel? I asked you to reduce the blur strength, not disable it. Created attachment 165627 [details]
desktop effects settings
see the attached screenshot
make sure that "background contrast" is unchecked
then click the configure button next to "blur" to reduce the blur strength

A possibly relevant merge request was started @ https://invent.kde.org/plasma/kwin/-/merge_requests/5132 Ack, I can reproduce that. I had background contrast effect disabled :D Git commit 6d0f1fedc0d1193c19e6946f72273eb6d00cd91f by Vlad Zahorodnii. Committed on 07/02/2024 at 13:53.

Created attachment 164973 [details] screenshot of the problem SUMMARY Blur effect texture flipped on 180 degrees. STEPS TO REPRODUCE 1. Connect the monitor with the orientation rotated 90 degrees counterclockwise 2. Open any app or widget (for example - network Widget on default panel) with blur effect OBSERVED RESULT Blur texture appears upside down EXPECTED RESULT Blur texture is displayed according to reality SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 5.92.0 KDE Frameworks Version: 5.248.0 Qt Version: 6.7.0 Kernel Version: 6.7.0-zen3-1-zen (64-bit) Graphics Platform: Wayland Processors: 16 × AMD Ryzen 7 2700X Eight-Core Processor Memory: 31.3 GiB of RAM Graphics Processor: NVIDIA GeForce RTX 3060/PCIe/SSE2 ADDITIONAL INFORMATION Everything is displayed correctly on the monitor without screen rotation.
