Double shadow in `TPaveText` #17076

When producing images, double shadow for TPaveText is produced. Which normally should not happen.

Reproducer

From $ROOTSYS, starts:

root --web=off tutorials/hsimple.root -e 'gStyle->Reset(); hpx->Draw(); c1->SaveAs("hpx.png")'

Double shadow disappears when TCanvas modified - like after resize

As Serguey mentioned elsewhere the following lines also show the problem:

{
   auto h1 = new TH1I("h1","histogram title", 100, -5, 5);
   h1->FillRandom("gaus", 10000);
   gStyle->SetTitleBorderSize(5);
   h1->Draw();
}
