Created attachment 143351 [details] backtrace of the crash SUMMARY When I try to open a file with 16-bit int depth color profile, Krita crashes upon loading the file. 8-bit documents are opened correctly. I'm attaching a test file triggering the crash and a backtrace. STEPS TO REPRODUCE 1. Open a file with 16-bit depth profile OBSERVED RESULT Krita crashes. EXPECTED RESULT The file is opened.

Hm, this is android specific and it's an assert on the availability of opengl es. Sharaf, can you take a look?
This seems to have been caused by: https://invent.kde.org/graphics/krita/-/commit/c6c82dda15037869b26a02e19f3f7900a06cce3b. It seems the `GL_EXT_texture_storage` is not available on Android's OpenGL ES2/3 implementation. I'm not sure whether all implementations are guaranteed to have this extension or not, CCing amyspark.

(In reply to sh_zam from comment #3) > I'm not sure whether all implementations are guaranteed to have this > extension or not, CCing amyspark. I need to revise my spam filters... `GL_EXT_texture_storage` not only is a prerequisite for using any float textures in GLES 2, it's also widely available on hardware (judging from a Google search here). My changes also log the available extensions at launch, so Sharaf or Anna, can you post here what your tablets support? The data should be available in Help / Show system information for bug reports.
Created attachment 144002 [details] system information for bug reports (android) I'm attaching the system information. The device is a Samsung Galaxy Tab S6, if that's relevant. Thanks for looking into it :)
Thanks Anna! I now know what the problem is; you're running an ES3 device, for which GL_EXT_texture_storage is indeed not required (as it's provided for by the standard). Previously, it didn't crash because the ES3 case was covered by the desktop OpenGL clauses in initializeRGBA16FTextures; however, it would've crashed later if your device didn't have EXT_color_buffer_float. I'll send the corrections to Sharaf's patch as soon as I have tested them here.

OpenGL: fix broken usage of OpenGL ES U16 surface Back in eb920fadf553ca827b4ff783ff6f82395bc88144, I added this fallback for ES2 clients that did provide U16 surfaces. However, I forgot to specify that the texture format has to be RGBA. This slipped past my testing at the time because selecting OpenGL ES on desktops wasn't available until 5464b09830.
