graphicsoffload: Importing dmabufs as GL texture produces pixelated textures
This is with GTK cda4ec48 on AMD Radeon RX 550 / 550 Series (radeonsi, polaris12, LLVM 18.1.1, DRM 3.57, 6.8.7-300.fc40.x86_64)
.
First screenshot is unscaled with offloading, second is without offloading (disabled via the property).
Colors should be obvious by direct comparison, because of the high resolution the other problem is not very easy to see. Zoomed in screenshots (in the same order) to make that clearer
