V Stuart Foote <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |RESOLVED Resolution|--- |WORKSFORME --- Comment #5 from V Stuart Foote <[email protected]> --- Going to call this => WFM, seems it is a resource issue with the shared graphics memory. Some dev might have the cycles to dig into the memory cache/flush and vk paint/erase/draw sequence as the font previews are scrolled, but this issue goes away when not running skia/Vulkan rendering which will become default at 26.2.5. For completeness, finally got a moment to get onto my workstation with a more robust dGPU and more resources. No issue (26.2.4, or 26.8.0.1) with rendering of the font list with previews scrolling it up or down by its "thumb" with this mainstream nVidia dGPU with sufficient resources, 8Gb of physical/48Gb shared display RAM: =-dxdiag.exe-= Driver Name: C:\WINDOWS\System32\DriverStore\FileRepository\nvdd.inf_amd64_55661cb7fab2ea8e\nvldumdx.dll,C:\WINDOWS\System32\DriverStore\FileRepository\nvdd.inf_amd64_55661cb7fab2ea8e\nvldumdx.dll,C:\WINDOWS\System32\DriverStore\FileRepository\nvdd.inf_amd64_55661cb7fab2ea8e\nvldumdx.dll,C:\WINDOWS\System32\DriverStore\FileRepository\nvdd.inf_amd64_55661cb7fab2ea8e\nvldumdx.dll Driver File Version: 32.00.0015.9595 (English) Driver Version: 32.0.15.9595 DDI Version: 12 Adapter Attributes: HARDWARE_TYPE_GPU,D3D11_GRAPHICS,D3D12_GRAPHICS,D3D12_CORE_COMPUTE,D3D12_GENERIC_ML,D3D12_GENERIC_MEDIA Feature Levels: 12_2,12_1,12_0,11_1,11_0,10_1,10_0,9_3,9_2,9_1,1_0_CORE Driver Model: WDDM 3.2 =-VulkanInfo.exe-= Device Properties and Extensions: ================================= GPU0: VkPhysicalDeviceProperties: --------------------------- apiVersion = 1.4.329 (4211017) driverVersion = 595.95.0.0 (2497167360) vendorID = 0x10de deviceID = 0x2803 deviceType = PHYSICAL_DEVICE_TYPE_DISCRETE_GPU deviceName = NVIDIA GeForce RTX 4060 Ti pipelineCacheUUID = 97b7c0f3-ee35-b817-1a38-098fb1dabde0 So, guess it really is simply a resource issue with Vulkan rendering, for this iGPU, 0x8a52 runs out of its 128Mb physical/8Gb shared of display memory redrawing before we flush its buffers. deviceID = 0x8a52 deviceType = PHYSICAL_DEVICE_TYPE_INTEGRATED_GPU deviceName = Intel(R) Iris(R) Plus Graphics -- You are receiving this mail because: You are the assignee for the bug.
