    <p><strong>Reproduction steps: Run a scan, open Tasks/Reports, maximize window on high resolution screen (2560x1600 px at 115% here).</strong></p>
    <p><span></span></p>
    <p><strong>Actual result: Output is not GPU accelerated, high CPU load with one thread/core being maxed out, high lag for input commands (mouse, keyboard)</strong></p>
    <p><span></span></p>
    <p><strong>Expected Result: Low CPU load, smooth operation</strong></p>
    <p><strong></strong></p>
    <p><strong>Animated GIF: Reports CPU load + lag (4.16% = 1 out of 24 logical cores maxed out) </strong></p>

      <p>Hello! </p>
      <p>Can you please reproduce it on new 11.7.0.658 build ? </p>
      <p>we will need: </p>
      <p> - GSI (<a href="https://support.kaspersky.com/common/diagnostics/3632)" target="_blank" rel="noopener">https://support.kaspersky.com/common/diagnostics/3632)</a></p>
      <p>- product traces</p>
      <p>- xperf traces (<a href="https://box.kaspersky.com/f/9f88c621cb7c4583bdbc/" target="_blank" rel="noopener">archive</a>,<span> </span><a href="https://box.kaspersky.com/f/e0b7e61e24f5485680b7/" target="_blank" rel="noopener">guide</a>) </p>

        <p>@Dmitriy, which part of the GSI and traces do you need exactly? I do not like having to share everything about my computer to report issues.</p>
        <p></p>
        <p>I tested 658 and the CPU load is still high when the Tasks/Reports windows are maximized. Desktop Windows Manager also shows increased GPU load then, albeit still low by my NVidia RTX 2700 Super's standards (clocks remain at idle frequencies). GPU load <em>is </em>higher than scrolling this forum thread in Firefox, though.</p>

          <p>@timur-born</p>
          <p>We need product traces & xperf traces, that can help to our developers to understand situation. GSI will helpful<span>, but not mandatory at this moment. I can't say what part of traces is needed for developers, because we need to find where is the problem first.</span></p>

            <p>I understand. Did you try to reproduce the behavior on your computers already? Could you not reproduce it on your hardware then?</p>
            <p></p>
            <p>Main problem seems to be that UI dialogs that show scan progress, aka Tasks and the Reports "Scan" tab, cause high CPU load while updating the progress information while a scan is active.</p>

              <p>@timur-bornHi. We can't reproduce problem on our side. It can depend of OS settings or hardware configuration. Can you send traces to us for issue investigation? </p>

                <p>Additionally to my AMD 5900X system I reproduced this very easily on two more Windows computers with different hardware and software setups, a bootcamped Macbook Pro (W10 21H1) and 9900K desktop (W10 20H2), both using Intel GPUs. Installed KES, started a full scan via Tasks and maximized the Tasks window. The larger the window the higher the load, so it likely is desktop resolution dependent (2560x1600 max on all my computers).</p>
                <p></p>
                <p>Intel 9900K desktop:</p>
                <p><img src="https://i.imgur.com/HjBwQkO.png" alt="" width="552" height="62" /></p>
                <p></p>
                <p>Apple MacBook Pro 13" (2018), i5 2,3 GHz:</p>
                <p><img src="https://i.imgur.com/Pb4sRMO.png" alt="" width="645" height="81" /></p>
                <p></p>
                <p>So instead of using xperf traces you may want to try to reproduce this on your side again, because that's likely better for analysis.</p>
