<html><head></head><body>Hello, I'm running a QtQuick application using shaders on an older Intel(R) Atom(TM) CPU N270 @ 1.60GHz with Intel Corporation Mobile 945GM/GMS/GME, 943/940GML Express Integrated Graphics Controller. My setup is * Ubuntu 16.04 (32-bit) * Qt 5.9.2 * Mesa: 17.4.0 * Intel i8xx, i9xx display driver: 2.99.917 * XServer: 1.18.4 The test application is the QtQuick samegame example. When I start the app with the INTEL_DEBUG=perf env variable i get the following messages <pre class="mcntmcntcode-java">.... ENTER FALLBACK 10000: Program LEAVE FALLBACK Program i915_program_error: Exceeded max nr indirect texture lookups (6 out of 4) ... and the CPU load goes up to 100% and the app reacts very slow. Btw. is there another debugging/tracing configuration which i can use to narrow down the problem a bit more? With the perf or oprofile tool I see that the most CPU time is consumed by i915_dri.so. Are there any known regressions regarding QtQuick/Qt 5/Shaders and the i915 driver on Ubuntu 16.04. </pre> Regards - Benjamin Federau -- M.Sc.
