NGL/Vulkan struggling with larger textures in Loupe
-
Vulkan performance is noticeably going down with trilinear filtering. Reproducible in GTK Demo where dragging the zoom slider around gives a sluggish reaction. Other filters seem to be okay when testing with 16382 × 3682 pixels (panorma.jpg).
-
Vulkan and NGL are going < 10fps for zoom and pan in Loupe with an image that has 20000 × 17000 pixels (large.jpg). For GL I have my max (70) fps. The image does not load in GTK demo.
-
When switching to large.jpg from another image in Loupe, Loupe will not show the texture.
All tested with Loupe nightly flatpak.
