The attached qml profiler results lead to a very sluggish profiler experience in the latest commercial Qt Creator release. Especially scrolling is noticeably slow and Qt Creator shows high CPU consumption.
perf points towards QSGBatchRenderer::Renderer::uploadBatch, with 76% of the samples spent in during horizontal scrolling.
Similarly, the performance goes down when one activates the tooltip on hover and moves the cursor over the results for the attached data file.
